AssemblyAI is a leading Voice AI API company that provides developers with advanced speech-to-text capabilities. It is designed to transcribe audio files into text with high accuracy, offering features such as real-time transcription, speaker diarization, and more. This tool is widely used in applications that require audio data processing, such as call analytics, voice commands, and media content transcription.
When using AssemblyAI, one common issue developers encounter is the "Unsupported Audio Format" error. This symptom manifests when the API returns an error message indicating that the audio file format is not supported. As a result, the transcription process cannot proceed, and no text output is generated.
The "Unsupported Audio Format" error typically occurs because the audio file being sent to AssemblyAI is in a format that the API does not recognize or support. AssemblyAI supports specific audio formats, such as WAV and MP3. If the audio file is in a different format, the API will not be able to process it, leading to this error.
Some common unsupported formats include OGG, FLAC, and AAC. If your audio file is in any of these formats, you will need to convert it to a supported format before sending it to the API.
To resolve the "Unsupported Audio Format" error, you need to convert your audio file to a format supported by AssemblyAI. Here are the detailed steps to do so:
First, determine the current format of your audio file. You can do this by checking the file extension or using a tool like MediaInfo to inspect the file's properties.
There are several tools available for converting audio files. Some popular options include:
Using FFmpeg, you can convert your audio file to WAV format with the following command:
ffmpeg -i input_file.ogg output_file.wav
Replace input_file.ogg
with the path to your audio file and output_file.wav
with the desired output path.
Once the conversion is complete, upload the new WAV or MP3 file to AssemblyAI for transcription. Ensure that the file meets any additional requirements specified by the API, such as sample rate and bit depth.
By following these steps, you can resolve the "Unsupported Audio Format" error and successfully use AssemblyAI to transcribe your audio files. For more information on supported formats and other API features, visit the AssemblyAI documentation.
