Overview

A decision pattern for selecting the audio input source (file upload, cloud URL, or audio stream) for speech-to-text transcription based on availability and processing requirements.

Description

Audio Source Selection determines how audio reaches the STT system. Three modes are available:

• File upload: Local file sent as multipart form data (batch STT)
• Cloud storage URL: HTTPS URL of audio (batch STT, up to 2GB)
• Audio stream/URL: Live audio for realtime STT (via manual chunks or URL+ffmpeg)

The choice depends on where the audio resides and whether real-time processing is needed.

Usage

Choose file upload for local files, cloud URL for remote files, and streaming for live audio.

Theoretical Basis

# Decision pattern
if audio_is_local_file:
    result = stt.convert(file=open(path, "rb"))
elif audio_is_remote_url:
    result = stt.convert(cloud_storage_url=url)
elif audio_is_live_stream:
    connection = await stt.realtime.connect(options)
