Voices - RunAnywhere Documentation

let voices = try await RunAnywhere.tts.voices()

for voice in voices {
    print(voice)
}

Signature

func voices() async throws -> [Voice]

The list reflects the loaded speech model. Load a different TTS model and the list changes, so call it after the model is in place rather than at launch.

Selecting one

let options = TtsOptions(voice: "en_US-amy-medium")
let handle = try await RunAnywhere.tts.speak("Hello", options: options)

With voice unset, the model’s own default is used.

Language and voice are separate

TtsOptions.language sets the language code; voice picks a speaker. A multi-voice model exposes several speakers for one language, and a single-voice model ignores voice entirely.

TtsOptions(voice: "en_US-amy-medium", language: "en-US", speed: 1.0, pitch: 1.0)

Letting a person choose

@MainActor
@Observable
final class VoicePicker {
    var voices: [Voice] = []
    var selected: String?

    func load() async throws {
        voices = try await RunAnywhere.tts.voices()
        selected = voices.first.map(String.init(describing:))
    }

    func preview() async throws {
        guard let selected else { return }
        _ = try await RunAnywhere.tts.speak(
            "This is how I sound.",
            options: TtsOptions(voice: selected)
        )
    }
}
