About Sprag

Sprag provides voice AI tools for developers building spoken interfaces and conversational agents. Its platform offers speech recognition, text to speech, voice cloning, and voice design, with a browser studio for trying voices and generating audio. Developers can build a speech-to-speech agent or connect separate transcription, language model, and speech generation stages when they need more control.

An OpenAI-compatible API and integrations with LiveKit and Pipecat help connect these capabilities to an application. Teams can use preset voices or create their own, work across supported languages, and inspect transcripts and individual pipeline steps. Sprag offers hosted infrastructure and self-hosted deployment options for different operational requirements.
