Overview

Receive audio in chunks as it’s generated, allowing playback to start immediately. Reduces latency compared to TTS REST.
Passing numbers, IDs, dates, or currency as raw strings causes mispronunciations. See the Input Formatting Guide for correct formatting of phone numbers, account numbers, PINs, Aadhaar, vehicle registration numbers, GSTIN, currency, and more.
