@juspay/neurolink/dist/voice/index.d.ts

The pipe layer of an AI nervous system: one interface connecting provider neurons to your application, across three inference types — generate, stream and decide. `decide` returns typed, calibrated judgements from a non-generative model (~400ms, ~$0.00002

/**
 * Voice Module - Unified Voice/Speech Integration for NeuroLink
 *
 * Provides TTS (Text-to-Speech), STT (Speech-to-Text), and
 * Realtime Voice capabilities across multiple providers.
 *
 * Use TTSProcessor (src/lib/utils/ttsProcessor.ts) for TTS.
 * Use STTProcessor (src/lib/utils/sttProcessor.ts) for STT.
 * Use RealtimeProcessor for realtime voice sessions.
 *
 * Importing this module does NOT register any handlers as a side effect.
 * Call `registerDefaultTTSHandlers()` / `registerDefaultSTTHandlers()` /
 * `registerDefaultRealtimeHandlers()` explicitly (or go through
 * `ProviderRegistry.registerAllProviders()`, which every documented
 * `NeuroLink` entry point already calls) to register every shipped handler
 * whose backing API key is present in `process.env`. Registration is
 * idempotent and silently skipped on failure.
 *
 * @module voice
