Speechmatics Unsupported Sample Rate

Audio file has a sample rate not supported by the API.

Understanding Speechmatics: A Leading Voice AI API

Speechmatics is a cutting-edge Voice AI API company that provides robust speech-to-text solutions. It is widely used by engineers and developers to convert audio into accurate text transcriptions. The tool supports multiple languages and is designed to handle various audio formats, making it a versatile choice for applications requiring voice recognition capabilities.

Identifying the Symptom: Unsupported Sample Rate

When using Speechmatics, you might encounter an error indicating an 'Unsupported Sample Rate'. This symptom typically manifests when the audio file you are trying to process has a sample rate that the API does not support. As a result, the transcription process fails, and you receive an error message.

Exploring the Issue: Why Sample Rate Matters

The sample rate of an audio file determines how many samples of audio are captured per second. Speechmatics requires audio files to be in a specific sample rate to ensure optimal processing and transcription accuracy. Commonly supported sample rates include 16kHz, which is standard for many speech recognition applications. If your audio file's sample rate is not supported, the API cannot process it, leading to the error.

Common Supported Sample Rates

  • 16kHz
  • 8kHz
  • 44.1kHz

Steps to Resolve the Unsupported Sample Rate Issue

To fix the unsupported sample rate issue, you need to convert your audio file to a supported sample rate. Here are the detailed steps to achieve this:

Step 1: Check the Current Sample Rate

First, determine the current sample rate of your audio file. You can use a tool like FFmpeg to inspect the audio file. Run the following command in your terminal:

ffmpeg -i your_audio_file.wav

This command will display the audio file's properties, including the sample rate.

Step 2: Convert the Audio File

Once you know the current sample rate, use FFmpeg to convert the audio file to a supported sample rate, such as 16kHz. Execute the following command:

ffmpeg -i your_audio_file.wav -ar 16000 output_audio_file.wav

This command converts the audio file to a 16kHz sample rate, saving it as 'output_audio_file.wav'.

Step 3: Re-upload and Test

After conversion, upload the new audio file to Speechmatics and test the transcription process again. The error should be resolved, and the API should now process the file successfully.
