Azure AI Speech text-to-speech (REST POST /cognitiveservices/v1, SSML body).

Azure AI Speech text-to-speech (REST POST /cognitiveservices/v1, SSML body).

Requests the raw-24khz-16bit-mono-pcm output format, so GeneratedAudio.data is headerless 24 kHz, 16-bit, mono PCM described by an honest AudioMeta. Write it out with org.llm4s.speech.io.WavFileGenerator.saveAsWav.

options.voice overrides the configured voice name; options.language sets xml:lang (default: the locale prefix of the voice name, else en-US); options.speakingRate becomes a prosody rate.

Value parameters

ElevenLabs text-to-speech (POST /v1/text-to-speech/{voice_id}).

Requests output_format=pcm_24000 (raw 24 kHz, 16-bit, mono little-endian samples), so GeneratedAudio.data is headerless PCM described by an honest AudioMeta. Write it out with org.llm4s.speech.io.WavFileGenerator.saveAsWav. options.voice overrides the configured voice id.

Value parameters

final class OpenAITTSClient(config: TTSConfig, httpClient: Llm4sHttpClient) extends TextToSpeech

OpenAI text-to-speech (POST /v1/audio/speech).

OpenAI text-to-speech (POST /v1/audio/speech).

Asks for response_format = pcm, which OpenAI documents as raw 24 kHz, 16-bit, mono little-endian samples, so GeneratedAudio.data is headerless PCM described by an honest AudioMeta - the same shape org.llm4s.speech.tts.Tacotron2TextToSpeech produces. Write it out with org.llm4s.speech.io.WavFileGenerator.saveAsWav.

options.voice overrides the configured voice; options.speakingRate is sent as speed (OpenAI accepts 0.25 to 4.0).
