Create speech with HeyGen’s native and catalog voices, discover available voices, and convert audio with timing preserved. The skill also supports timestamped and streamed output, with explicit selection of the voice model or catalog engine.
HeyGen native Voice1 and catalog speech, voice discovery, timestamps, and streaming.
Run score Not tested
See how to installThis skill uses HeyGen speech generation to turn text into audio. It treats native voices and catalog voices as separate systems, with an explicit choice of model or engine. You can list available voices and convert existing audio with timing preserved, using an active instant workspace voice. Results are WAV files. For streamed output, the skill assembles the audio parts and saves timestamps as alignment information.
Use it to create narration, check which voices are available, or convert existing audio to a selected instant voice in a workspace while keeping its timing. Voice discovery is available for native voices, while catalog speech uses its own voice IDs and engine selection.
Native voice IDs and catalog voice IDs are not interchangeable. Professional voices require the Voice1 model and cannot be used with Turbo. The skill does not silently switch to an older speech API endpoint; select the model or engine explicitly. The supplied materials state that Turbo Free is available through November 30, 2026.

heygen_tts: native HeyGen Voice1 / Turbo / Turbo Free. Native ACTIVE public,
instant or professional voices from /v3/models/audio/voices. Professional
voices require Voice1 (not Turbo). Output is44.1kHz WAV; text limit5,000 chars.heygen_catalog_tts: catalog voices from /v3/voices; explicit engine selection
on /v3/voices/speech (Starfish, HeyGen Voice, or ElevenLabs). These voice IDs
are not interchangeable with native clone IDs.heygen_voice_convert: timing-preserving conversion with an ACTIVE instant
workspace voice via /v3/models/audio/sts.Read the October23 provider guide for current request fields, output paths, timestamp/SSE handling, pricing, and retry behavior. Do not silently fall back between native models, catalog engines, or hosts. Turbo Free is promotional through November30,2026 and has shared capacity limits.
