Moonshine Voice is an open-source on-device AI toolkit providing very low latency speech-to-text, intent recognition, and text-to-speech for building real-time voice agents and interfaces. It ships models from 1MB up to Whisper-Large-V3-beating accuracy, with a unified API across Python, JavaScript/WASM, iOS, Android, macOS, Linux, Windows, and Raspberry Pi.

Use cases

• transcribe live microphone audio to text with low latency
• build a real-time voice agent that responds while the user is still talking
• run speech-to-text entirely on-device without API keys or cloud calls
• convert text to natural speech in the browser or on mobile
• clone a custom voice from a few seconds of recorded speech
• add intent recognition to a spoken voice interface
• build a dictation or meeting-notes app with speaker-aware transcripts

When to choose

• you need low-latency streaming transcription for live voice agents
• privacy matters and audio must never leave the device
• you need one speech stack across many platforms including embedded and WASM
• you want tiny models for resource-constrained devices like Raspberry Pi
• you want MIT-licensed speech models without per-call cloud costs

When to avoid

• you need batch offline transcription of large audio archives where latency is irrelevant
• you need the widest language coverage, since streaming models focus on English and a few languages
• you require commercial use of the legacy non-streaming non-English models, which carry a non-commercial license
• you need heavy-duty NLU beyond intent recognition in a full conversational AI platform
