Use cases

Two glowing nodes joined by a taut thread of light, one answering the other

Narration and voice-over

Cast a narrator once and keep the same voice across every cut, pickup, and revision.

A ribbon of light splitting into parallel ribbons that stay in step

Localized voice-over

Run the same script across many languages and keep one voice, so a brand survives translation.

Many small points of light scattered through depth, joined by faint threads

FAQs

What is Inworld TTS 2?
Inworld TTS 2 is Inworld's Realtime TTS-2 text-to-speech model, released on August 31, 2026. It reads a script in one of ninety-five ready-made voices, holds that voice identity across more than 100 languages, and returns audio at real-time speed.
How many voices and languages does it support?
Ninety-five ready-made voices across fourteen native languages, with crosslingual delivery across more than 100 languages. Any voice can speak any supported language, so a voice's native language tells you how it was cast rather than what it is limited to.
Can one voice speak more than one language?
Yes, and it can switch inside a single generation. The voice identity is held across the change, so a bilingual script comes back sounding like one speaker rather than two takes stitched together. That is what makes it practical for localized brand voice-over.
What makes it fast?
Median time to first audio is under 200 milliseconds. That moves text-to-speech out of the render-and-wait category, which is what makes it usable for interactive characters and live agents rather than only for voice-over you generate once.
What is the difference between Inworld TTS 2 and Inworld TTS 2 Flash?
They share the same ninety-five-voice catalog. Inworld TTS 2 gives the fullest read. Inworld TTS 2 Flash is the faster, lower-cost tier for volume work or drafts. You can switch between them without recasting the voice.
How long can a script be?
Up to 2,000 characters per generation. For anything longer, split the script into passages and generate them in sequence. The cast voice stays the same across them, so a long piece stays consistent.
How is it different from ElevenLabs on Morphic?
Both produce human-quality speech on Morphic. ElevenLabs is a full audio suite covering speech, music, and sound effects with fine-grained voice tuning. Inworld TTS 2 is speech only, and its advantages are latency and holding one voice across languages. Many creators use both, one for voice, the other for music and effects.
How do I use Inworld TTS 2 on Morphic?
Open Morphic, switch the prompt bar to Audio, and choose Speech. Pick Inworld TTS 2 as the model, choose a voice, paste your script, then generate. The audio lands on your Canvas alongside your video clips.
