FAQPage Schema
How do I transcribe audio files into text on the backend?

To transcribe audio into text on the backend, you send base64-encoded audio data to the server. The service processes the input and returns a plain text transcription of the speech.

What audio formats are supported for speech-to-text transcription?

Speech-to-text transcription supports common audio formats including WAV, MP3, and M4A. This broad compatibility allows you to process various meeting recordings, podcasts, and voice notes.

Can I use z-ai-web-dev-sdk for meeting transcription in backend services?

Yes, you can use z-ai-web-dev-sdk for meeting transcription in backend services. It accepts base64-encoded audio input and transcribes it into plain text.

How do I prepare audio files for server-side speech-to-text processing?

To prepare audio files for server-side speech-to-text processing, you must encode the audio data into base64 format. This encoded string is then sent to the backend for transcription.

What is the best way to convert voice notes into searchable text content?

The best way to convert voice notes into searchable text is using server-side speech-to-text transcription. This process decodes base64 audio and returns accurate plain text, enabling accessible and searchable content.

Are there limitations when processing large audio files for transcription?

When processing large audio files for transcription, the base64 encoding requirement may increase payload size and impact transfer speeds. The implementation handles common formats but relies on backend processing capacity for large inputs.
