5 ways to use Gemini text-to-speech (TTS) in your apps with Firebase AI Logic
SMRTR summary
A cooking app that reads Belgian Dutch recipe abbreviations aloud without sounding robotic. That's just one sign of how Google's Gemini text-to-speech technology is quietly reshaping what mobile and web apps can do.
Available now through Firebase AI Logic, Gemini TTS lets developers add natural, customizable voice generation directly into their apps, no complex server-side infrastructure required. Unlike conventional text-to-speech tools, Gemini uses a large language model that understands not just what to say, but how to say it, adjusting tone, pacing, accent, and even emotional mood.
The applications are surprisingly broad. A Finnish language coaching app uses it to simulate real-time conversation practice for immigrants preparing for national certification exams. Other developers are exploring hands-free navigation, accessibility features, interactive storytelling, and even fully synthesized multi-speaker podcasts.
Developers can choose from over 30 multilingual voices, with support for Swift, Kotlin, JavaScript, and several other languages. The tool is available today.
