Struct TtsManager 

pub struct TtsManager { /* private fields */ }

Central manager for per-agent TTS synthesis.

tts_providers are keyed by their dotted alias (<type>.<alias>). Per-instance voice overrides come from the voice field on each TtsProviderConfig. The agent_tts_provider field carries the resolved alias for the agent that owns this manager instance — empty means the agent doesn’t want TTS, and synthesize_for_agent fails loud rather than silently pick a default.

Implementations

impl TtsManager

pub fn from_config(config: &Config) -> Result<Self>

Build a TtsManager from [tts_providers.<type>.<alias>] instances in Config. Each instance is registered under its dotted alias key (<type>.<alias>). Failures to construct a particular instance are logged at warn but do not abort the manager. Build a TtsManager from [tts_providers.<type>.<alias>] instances. The manager’s resolved alias comes from the runtime-active agent’s tts_provider field — there is no global default-provider concept, so when no agent-bound resolution is available the manager refuses to silently pick a provider (synthesize fails loud).

pub async fn synthesize(&self, text: &str) -> Result<Vec<u8>>

Synthesize text using the runtime-active agent’s resolved tts_provider reference and the per-instance voice override (or default_voice as the per-instance fallback). Fails loud when the agent has no tts_provider configured — there is no global default-provider concept and this manager refuses to silently pick one.

pub async fn synthesize_with_provider( &self, text: &str, provider_alias: &str, voice: &str, ) -> Result<Vec<u8>>

Synthesize text using a specific dotted-alias model_provider and voice.

pub fn available_providers(&self) -> Vec<String>

List dotted aliases of all initialized tts_providers.
