AI.FM – Text to Speech

关于这款应用

AI.FM is a text-to-speech application developed by Joseph Works Limited for iOS and macOS. It utilizes advanced AI models to convert written text into natural-sounding audio. The app distinguishes itself by allowing users to provide plain-language instructions to define the voice’s persona, tone, or style, such as requesting a ‘sympathetic customer service agent’ voice. This capability aims to move beyond generic robotic readings toward more expressive and tailored audio output.

Key functionalities include selecting from multiple distinct male and female AI voices, adjusting playback speed for comfortable listening, and exporting generated audio files for sharing. The interface is designed for simplicity, requiring users to type or paste text along with their delivery instructions. The app supports various use cases, including content creation for videos and podcasts, educational narration, accessibility for reading long texts like textbooks, and prototyping voice agents for customer experience design. While it offers high-quality voice generation, some user feedback indicates limitations regarding offline functionality and handling very large documents.
