Google Speech API is a powerful tool that enables developers to convert audio to text by applying neural network models in an easy-to-use API. It supports various languages and can be integrated into applications to enhance user interaction through voice recognition.
When using the Google Speech API, you might encounter an error message indicating an 'Invalid sample rate'. This error typically arises when the audio file you are trying to process has a sample rate that is not supported by the API.
The 'Invalid sample rate' error occurs because the audio file's sample rate does not match the supported rates by Google Speech API. The API requires audio files to be in specific sample rates, such as 16kHz, to ensure accurate processing and transcription.
To fix the 'Invalid sample rate' error, you need to convert your audio file to a supported sample rate. Below are the steps to achieve this:
First, verify the current sample rate of your audio file. You can use tools like FFmpeg to check the sample rate:
ffmpeg -i your_audio_file.wav
Look for the 'Hz' value in the output to determine the current sample rate.
Once you know the current sample rate, use FFmpeg to convert it to a supported rate, such as 16kHz:
ffmpeg -i your_audio_file.wav -ar 16000 converted_audio_file.wav
This command changes the sample rate to 16kHz, which is compatible with Google Speech API.
After conversion, verify the new sample rate to ensure it matches the required specifications:
ffmpeg -i converted_audio_file.wav
Confirm that the 'Hz' value is now 16000.
By following these steps, you can resolve the 'Invalid sample rate' error and ensure your audio files are compatible with Google Speech API. For more detailed information, refer to the Google Speech-to-Text Documentation.
