Funciones

Text to speech

Generates spoken audio from text input.

text_to_speech

Streaming

HTTP chunked streaming (POST /tts/v1/voice:stream, newline-delimited JSON with base64 audio) and a bidirectional WebSocket API.

streaming

Async long-text synthesis

Async job API (POST /tts/v1/voice:synthesizeAsync) accepts up to 100,000 characters per job (On-Demand accounts capped at 10,000) and stitches the audio server-side; the sync and streaming APIs cap text at 2,000 characters.

async_long_text

Batch synthesis

Batch job API (POST /tts/v1/voice:synthesizeBatch, marked Preview) accepts up to 10,000 items of 100,000 characters each, capped at 10,000 characters per whole batch on On-Demand accounts, and is metered 20% below realtime synthesis on every plan.

batch

Word timestamps

timestampType=WORD returns timestampInfo.wordAlignment with per-token start and end times, and CHARACTER returns characterAlignment.

word_timestamps

Phoneme and viseme timing

WORD timestamps include phoneticDetails with IPA phone symbols, durations and viseme symbols for lip-sync.

visemes

Instant voice cloning

High-quality instant voice cloning (IVC) is supported.

instant_voice_cloning

Multilingual

200+ languages and locales, with cross-lingual synthesis and voice localization.

multilingual

Speaking rate control

audioConfig.speakingRate accepts 0.5-1.5 (1.0 = native speed).

speed_control

Non-verbal tags

Bracketed non-verbal sounds such as [laugh] and [sigh] work on both TTS-2 models.

non_verbal_tags

Synthesis context

synthesisContext.previousRequests supplies prior turns' text as context.

synthesis_context

Natural-language steering

Bracketed instruction tags and the request-level instruction field direct delivery, and a tag persists until changed or [reset].

instruction_steering

Delivery mode

deliveryMode (STABLE, BALANCED or CREATIVE) trades consistency against emotional range and defaults to BALANCED.

delivery_mode

Professional voice cloning

Professional Voice Cloning is documented as supported on inworld-tts-2 only.

professional_voice_cloning
