How It Works
Copilot Audio Expressions streamlines the audio creation process through an intuitive, efficiency-focused workflow designed for immediate results.
Begin by inputting your text content directly into the platform interface, whether it’s a script, narrative, or any written material you want to convert to audio. Next, select your preferred generation mode – choose Emotive Mode for detailed control over emotional delivery and pacing, or Story Mode for comprehensive narrative generation with automatic optimization. Configure voice and style preferences by selecting from the available voice options and emotional styles that best align with your content’s purpose and audience. The AI then processes and generates expressive audio within seconds, leveraging the MAI-Voice-1 model’s advanced capabilities to create natural, emotionally appropriate speech. Preview the generated audio using the integrated player to ensure quality and alignment with your expectations before downloading the final MP3 file for immediate use in your projects, presentations, or distribution channels.
