About

Copilot Audio Expression is an experimental feature within Microsoft’s Copilot Labs that transforms written text into expressive, natural-sounding voiceovers. Users can type or paste a script and choose between Emotive Mode, which allows them to select specific voice styles like Oak or expressive tones, and Story Mode, which blends multiple voices to deliver a dynamic narrative experience. The tool’s AI can reformulate content to feel engaging and nuanced, often adding subtle expressive flourishes. It currently supports English and can generate short audio clips, up to roughly a minute, in MP3 format, playable directly via the browser and downloadable without requiring a login. The interface includes an integrated web player for instant preview.

About

The most cost-effective, ultra-realistic text-to-speech API. It sounds more natural-sounding audio than AWS Polly, Microsoft Azure, IBM Watson, and Google Wavenet, and it costs 2 to 4 times less. For interactive applications, the API can return audio in 0.5 seconds for up to 45 seconds of audio (500 characters). For long-form applications, it can product up to 10 hours of audio in 15 minutes (500,000 characters).
