Exploring the Issue: Audio Duration Constraints

The 'Invalid Audio Duration' error occurs when the audio file you are trying to process exceeds the duration limits set by Speechmatics. This could mean the audio is either too short or too long. The API documentation provides specific guidelines on the permissible audio duration, which must be adhered to for successful processing.

Understanding the Error Code

The error code associated with this issue is typically a client-side error, indicating that the input does not meet the API's requirements. It is crucial to refer to the Speechmatics API documentation to understand the exact duration limits.

Steps to Resolve the Invalid Audio Duration Issue

To resolve this issue, follow these actionable steps:

Step 1: Verify Audio Duration

First, check the duration of your audio file. You can use tools like FFmpeg to determine the length of the audio. Run the following command to get the duration:

ffmpeg -i your_audio_file.wav

Look for the 'Duration' field in the output.

Step 2: Adjust Audio Length

If the audio file is too long, consider trimming it to fit within the acceptable range. You can use FFmpeg to trim the audio:

ffmpeg -i your_audio_file.wav -ss 00:00:00 -t 00:05:00 trimmed_audio_file.wav

This command trims the audio to the first 5 minutes.

Step 3: Re-upload the Audio

Once the audio file is within the acceptable duration, re-upload it to the Speechmatics API for processing. Ensure that the file format and other parameters meet the API's requirements.
