Identifying the Symptom: Audio File Too Long

When using Speechmatics, you might encounter an error indicating that the audio file is too long. This symptom typically manifests as a failure to process the audio file, accompanied by an error message or code specifying the issue.

Exploring the Issue: Why Audio Length Matters

The error 'Audio File Too Long' occurs when the duration of the audio file exceeds the maximum length allowed by Speechmatics. This limitation is in place to ensure optimal performance and resource management during processing. Understanding the constraints of your chosen Speechmatics plan is crucial to avoid this issue.

Technical Explanation

Speechmatics imposes a limit on audio file duration to maintain processing efficiency and prevent system overload. Exceeding this limit triggers an error, halting the transcription process. For more details on file limitations, refer to the Speechmatics Support Page.

Steps to Fix the Issue: Splitting Audio Files

To resolve the 'Audio File Too Long' error, you need to split the audio file into smaller segments. Here’s how you can do it:

Step 1: Determine the Maximum Allowed Length

Check the documentation or your Speechmatics account settings to find the maximum allowed audio file length. This information is crucial for planning your file segmentation.

Step 2: Use Audio Editing Software

Utilize audio editing software like Audacity or FFmpeg to split the audio file. For example, with FFmpeg, you can use the following command to split a file into 5-minute segments:

ffmpeg -i input.mp3 -f segment -segment_time 300 -c copy output%03d.mp3

For more on using FFmpeg, visit the FFmpeg Documentation.

Step 3: Re-upload Segmented Files

Once the audio file is split into acceptable lengths, upload each segment individually to Speechmatics for processing. Ensure that each segment adheres to the maximum length requirement.
