Lokutor Text-to-Speech

Community-maintained integration. This service is built and maintained by lokutor-ai. Pipecat does not test or officially support it. Please report issues and request changes on the source repository. Learn more about community integrations.

Overview

LokutorTTSService generates speech from text using Lokutor’s text-to-speech API over a persistent WebSocket connection. Lokutor runs on CPU-only infrastructure and supports multiple languages (EN, ES, FR, PT, KO). The service outputs TTSAudioRawFrames.
