Speech Synthesis Voice Library

omnial/available-voices

Takes no input. Returns the synthetic voices available for speech synthesis: one row per voice with its voice id, its display name, the category it belongs to, a one-line description of how it sounds, and selection labels for accent, age, language, voice character and use case. Each row also carries a preview audio link, which ships only when it is on one of the audio hosts seen in testing and is otherwise null. Use the voice id to request speech in that voice.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/available-voices" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/available-voices" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/available-voices", input: { /* see input_schema */ }, dry_run: true })
