Chunking Longer Audio Files for Whisper Models on Groq
By Hatice Ozen | View in the Groq Cookbook
By default, our speech endpoints only support audio files up to 25MB via direct file uploads. If you have audio files that are longer than 25MB, you'll need to chunk your audio! In this tutorial, we'll learn how to process long audio files efficiently using chunking methods with Groq API. Breaking down audio files into manageable chunks is essential for reliable transcription of longer recordings while maintaining high accuracy.
Groq is great for processing long audio files thanks to its fast inference speeds and even hours of audio that we process into chunks can be transcribed in a matter of minutes. As such, we'll use Whisper Large V3 powered by Groq and learn how to:
- Preprocess audio files for optimal transcription
- Split audio files into manageable chunks
- Implement a smart overlap for our chunks
- Transcribe our chunks using Whisper Large V3
- Merge our results while properly handling overlaps
- Save our transcriptions in multiple formats for further handling
Sound exciting? Let's get chunking!
Step 1: Install Required Libraries
First, you'll need FFmpeg installed on your system since we'll need it for format conversion and one of our required libraries depends on it. You can install on your system with the following:
- Windows: Download from https://ffmpeg.org/download.html
- Mac:
brew install ffmpeg
- Linux:
sudo apt-get install ffmpeg
Now, let's install the libraries we'll need for audio processing and transcription. Although there are other libaries for audio manipulation, we'll use PyDub since it provides a high-level interface that can handle all the audio formats supported by Groq API through ffmpeg
, which is what we'll use for preprocessing our audio:
pip install groq
pip install pydub
Step 2: Import Required Libraries
Now that we've installed the libraries we need, let's import them:
from groq import Groq, RateLimitError # For interacting with Groq API
from pydub import AudioSegment # For audio processing and chunking
import json # For saving our transcription results (optional)
from pathlib import Path # For file path handling (optional)
from datetime import datetime # For timestamping our output files (optional)
import time # For tracking processing duration (optional)
import subprocess # For running FFmpeg commands
import os # For environment variables and file handling
import tempfile # For safe temporary file handling
import re # For regex checking during audio chunk merging
Step 3: Preprocess Audio to Downsample (Optional)
Whisper models require audio files to be 16,000 Hz mono format before transcribing for standardization and Groq API will re-encode audio files to these settings after recieving them. You may want to preprocess your audio files client-side if your original file is extremely large and you want to make them smaller without a loss in quality (i.e. without chunking, Groq API speech endpoints accept up to 25MB). We recommend FLAC for lossless compression.
Let's define a function called preprocess_audio
that takes our file path for any audio file as input and returns the path to a converted FLAC format file. We'll use Python's subprocess to run ffmpeg
with the proper arguments for reducing our audio file quality to 16kHz and converting to mono, or single audio channel.
We'll also use a few extra (but optional) parameters for suppressing FFmpeg version info and build details, only showing errors and suppressing warnings, and automatically overwriting our output file if it already exists to ensure we always get a fresh conversion:
def preprocess_audio(input_path: Path) -> Path:
"""
Preprocess audio file to 16kHz mono FLAC using ffmpeg.
FLAC provides lossless compression for faster upload times.
"""
if not input_path.exists():
raise FileNotFoundError(f"Input file not found: {input_path}")
with tempfile.NamedTemporaryFile(suffix='.flac', delete=False) as temp_file:
output_path = Path(temp_file.name)
print("Converting audio to 16kHz mono FLAC...")
try:
subprocess.run(o
'ffmpeg',
'-hide_banner',
'-loglevel', 'error',
'-i', input_path,
'-ar', '16000',
'-ac', '1',
'-c:a', 'flac',
'-y',
output_path
], check=True)
return output_path
# We'll raise an error if our FFmpeg conversion fails
except subprocess.CalledProcessError as e:
output_path.unlink(missing_ok=True)
raise RuntimeError(f"FFmpeg conversion failed: {e.stderr}")
Step 4: Create Function for Transcribing a Single Chunk
Now that our audio is downsampled, we can create a dedicated worker function for transcribing individual audio chunks that will be called by our main transcription controller function in Step 7. Our transcribe_single_chunk
function uses the Whisper Large V3 model via Groq API to transcribe one chunk at a time. Let's break down how our function handles each chunk:
- Uses Python's
tempfile
module for safe, automatic cleanup of temporary files - Uses
whisper-large-v3
via Groq API and specifies language as English andverbose_json
as the response format - Times Groq API calls to monitor performance
- Provides detailed progress tracking (current chunk transcribed vs. total chunks)
- Maintains consistent error handling and resource cleanup
We highly recommend specifying language
. Whisper analyzes the first 30 seconds of your audio to determine language, but this could result in errors from Whisper possibly choosing the wrong language, especially if your audio has background noise, music, or silence in that timeframe. Specifying language
will also help speed up requests since Whisper can forego audio analysis for determining language.
Tip: Setting response_format
to verbose_json
for Groq API transcription and translation endpoints provides timestamps for audio segments! It also provides avg_logprob
, compression_ratio
, and no_speech_prob
! See our official docs for more info.
Once the single chunk is transcribed, the function returns a tuple of the transcription result and the processing time.
def transcribe_single_chunk(client: Groq, chunk: AudioSegment, chunk_num: int, total_chunks: int) -> tuple dict, float]:
"""
Transcribe a single audio chunk with Groq API.
Args:
client: Groq client instance
chunk: Audio segment to transcribe
chunk_num: Current chunk number
total_chunks: Total number of chunks

"""
total_api_time = 0
while True:
with tempfile.NamedTemporaryFile(suffix='.flac') as temp_file:
chunk.export(temp_file.name, format='flac')
start_time = time.time()
try:
result = client.audio.transcriptions.create(
file=("chunk.flac", temp_file, "audio/flac"),
model="whisper-large-v3",
language="en", # We highly recommend specifying the language of your audio if you know it
response_format="verbose_json"
)
api_time = time.time() - start_time
total_api_time += api_time
print(f"Chunk {chunk_num}/{total_chunks} processed in {api_time:.2f}s")
return result, total_api_time
except RateLimitError as e:
print(f"\nRate limit hit for chunk {chunk_num} - retrying in 60 seconds...")
time.sleep(60)
continue
except Exception as e:
print(f"Error transcribing chunk {chunk_num}: {str(e)}")
raise
Step 5: Handle Chunk Overlaps in Audio Transcription
When dealing with chunked audio transcription, one of the biggest challenges is handling the transitions between chunks smoothly (which is the basis of this entire tutorial inspired by a conversation with one of the developers in our community, Jan Zheng - thank you for the insightful conversations!). This is because Whisper can sometimes cut words off mid-word at chunk boundaries, transcribe the same word slightly differently in adjacent chunks, and have varying accuracy at the beginning and end of chunks.
To handle these challenges, we'll explore two strategies for handling chunk overlaps:
- The Local Agreement strategy, or longest common prefix (LCP) approach for finding exact matches between chunks
- The longest common sequence algorithm with sliding window alignment for more robust matching
Initially, the LCP approach seemed promising as it can handle varying overlaps, but because of Whisper's nature and the possibility of mid-word cutoffs, this approach is too restrictive since it looks for exact word matches between chunks. Through testing and feedback from one of my teammates (shoutout to Graden), our implementation will be the longest common sequence algorithm that:
- Isn't restricted to just checking chunk boundaries
- Can handle both partial word and character-level matching
- Uses a weighted scoring system that combines number of matching words/characters, position-based weighting (via an epsilon value), and minimum threshold of 2 matches for reliability
- Is more fault-tolerant of Whisper's boundary transcription quirks
Let's look at a practical example of what we're dealing with and consider the following two chunks:
Chunk 1: "Hello my name ich"
Chunk 2: "mine name is Jonathan"
This is where our find_longest_common_sequence
function comes in and:
- Tries different alignments by sliding the sequences
- For each position: Count matching elements, calculate a score ((matches/position) + tiny position-based weight), and require at least 2 matches to consider the alignment
- Find the best alignment (in this case, "name")
- Take the left half from Chunk 1 ("Hello my") and the right half from Chunk 2 ("name is Jonathan")
- Combine the sequences while handling variations like "ich/is" and "my/mine" into a clean final result ("Hello my name is Jonathan")
def find_longest_common_sequence(sequences: listestr], match_by_words: bool = True) -> str:
"""

Args:

if len(left) != len(right):

# Add remaining sequence
total_sequence.extend(left_sequence)
# Join back into text
if match_by_words:
return ''.join(total_sequence)
return ''.join(total_sequence)
Step 5: Merge Audio Chunk Transcriptions
With our sequence alignment function ready, we can now implement the merge_transcripts
function that will combine all our chunks into a single coherent transcript. merge_transcripts
takes a list of chunk transcription results and processes them based on the available data:
- Processes both segment-level and word-level timestamps when available:
- Extracts and adjusts all word timestamps based on their chunk's starting position
- Preserves all word-level timing information regardless of segment presence
- Combines words from all chunks into a single coherent list
- For segment-level data, the function:
- Handles overlapping segments by merging them into a single segment with combined text
- Processes the boundaries between chunks using
find_longest_common_sequence
to create smooth transitions - Maintains detailed segment metadata including
temperature
,avg_logprob
,compression_ratio
, andno_speech_prob
- Creates a comprehensive output that includes:
- The complete transcript text
- All merged and properly timed segments with their metadata
- Word-level timestamps when requested
The function works with timestamp granularities containing only segments, only words, or both!

Step 6: Save Transcription Outputs
Now let's implement our helper function that handles our transcription outputs. This save_results
function creates a dedicated transcriptions directory to keep our outputs organized, uses timestamped filenames to prevent overwrites, and saves our results in multiple formats for different use cases: plain text, JSON, and segmented JSON for detailed timestamp information.
def save_results(result: dict, audio_path: Path) -> Path:
"""
Save transcription results to files.
Args:
result: Transcription result dictionary
audio_path: Original audio file path
Returns:
base_path: Base path where files were saved
Raises:
IOError: If saving results fails
"""
try:
output_dir = Path("transcriptions")
output_dir.mkdir(exist_ok=True)
timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")
base_path = output_dir / f"{Path(audio_path).stem}_{timestamp}"
# Save results in different formats
with open(f"{base_path}.txt", 'w', encoding='utf-8') as f:
f.write(result="text"])
with open(f"{base_path}_full.json", 'w', encoding='utf-8') as f:
json.dump(result, f, indent=2, ensure_ascii=False)
with open(f"{base_path}_segments.json", 'w', encoding='utf-8') as f:
json.dump(resultu"segments"], f, indent=2, ensure_ascii=False)
print(f"\nResults saved to transcriptions folder:")
print(f"- {base_path}.txt")
print(f"- {base_path}_full.json")
print(f"- {base_path}_segments.json")
return base_path
except IOError as e:
print(f"Error saving results: {str(e)}")
raise
Step 7: Create Transcription Engine and Assemble the Pipeline
Now comes the fun part - bringing all the pieces we built together with transcribe_audio_in_chunks
, which is our orchestrator function that takes our audio file, splits it into chunks, coordinates the transcription process, combines the chunked transcription outputs, and saves our results! Think of this function as the conductor of our transcription orchestra that makes sure every function, or part, plays its role at the right time.
While Whisper was trained on 30-second segments and the recommended chunk size is 30-60 seconds, this can vary and longer chunks can actually provide better results when using Groq API. For this tutorial, we're using 600-second (10-minute) chunks with a 10-second overlap for an optimal balance of:
- Reduced calls to Groq API (fewer chunks)
- Better transcription accuracy (longer context)
- Reliable word boundary handling
- Staying safely within the current 25MB per-request limit for Groq API transcriptions and translations
Why an Overlap? Overlapping chunks prevents our model from losing context at chunk boundaries and cutting words in half. Without an overlap, we might split right in the middle of a word or sentence, which would cause missing content, increased hallucinations, and transcription errors. By overlapping (typically 5-10 seconds), we ensure that words and context spanning chunk boundaries are captured completely.
Understanding Chunk Overlap and Overhead When we use overlapping chunks, we're actually processing some audio multiple times. For example, with our settings for this tutorial, each 600-second chunk has 10 seconds of overlap at the start and end. This means we're processing 620 seconds (600 + 10 + 10) for each 600-second chunk, which creates a 3.33% overhead (20 extra seconds). This is much more efficient than shorter chunks. For example, 60-second chunks with 5-second overlaps would have a 33.3% overhead!
Overhead matters because more overhead means more API calls, higher costs, and more potential for transcription errors at boundaries. More processing time is also a factor, but since we're using Groq API, the impact there is minimal.
You may have to pretend to be Goldilocks and find overlapping chunks that are just right for your typical use case. While too small of a chunk size could result in the model missing important context for transcription, too large of a chunk size could lead to potential degradation in accuracy. For a rapid-fire podcast conversation or interview, shorter chunks might work better. For a slow-paced lecture or meeting, longer chunks could be your answer. You need to find the chunk size that's just right!

"""

return final_result
# Clean up temp files regardless of successful creation
finally:
if processed_path:
Path(processed_path).unlink(missing_ok=True)
Step 8: Run the Pipeline!
After quite the adventure where we've learned about audio chunking, it's time to put our transcription orchestra into action and see how it performs with real audio files. Replace the "path_to_your_audio"
below with the path for a long audio file of your choice. Groq API supports flac
, mp3
, mp4
, mpeg
, mpga
, m4a
, ogg
, wav
, and webm
audio file formats, but since we are converting to FLAC before sending our request to Groq, you can process any format that FFmpeg can handle.
When you run this code, you'll get several types of output that help you track the transcription process:
- Progress Updates: The code provides real-time feedback about which chunk it's processing as well as the time ranges.
- Transcription Results: The code creates a directory called
transcriptions
that will have three different output files.
if __name__ == "__main__":
transcribe_audio_in_chunks(Path("path_to_your_audio"))
Conclusion
This wraps up our journey through audio chunking and transcription with the lightning-fast Groq API! Once you do get the transcriptions, make sure to review them and remember that audio chunking and transcribing is both an art and a science! While our pipeline above handles the science part well, you might need to adjust the art part (the chunks and overlaps) based on your specific audio. Don't be afraid to experiment further on your own with different parameters.
