Speechify is excited to announce the launch of Speechify On-Device iOS Voices, a new generation of AI voice models designed to run fully on a user’s device. This release represents a significant research milestone for Speechify, enabling high-quality text to speech playback with 100 percent local inference, without relying on an internet connection.
With on-device iOS voices, users experience instant playback with no lag and no buffering, even when completely offline. These are the same natural-sounding voices Speechify users already know and trust, now capable of running entirely on device while maintaining the quality, clarity, and expressiveness previously available through cloud-based models.
Instant, Secure Playback Anywhere
Speechify On-Device iOS Voices is built for moments when connectivity is limited or unavailable. Whether users are flying, commuting underground, traveling internationally, or spending time in areas with unreliable service, Speechify continues reading without interruption.
Because inference happens locally on the device, audio playback begins immediately and remains responsive at all times. All processing stays on the user’s phone, providing a more private and secure listening experience while removing dependence on network availability.
Advancing Edge-Based AI Voice Technology
To make on-device playback possible, Speechify’s research team adapted its most advanced and compute-intensive voice models to run efficiently on smartphones without sacrificing audio quality. This required changes to model architecture to preserve the human sound, natural cadence, and expressiveness users expect while achieving fully local performance.
The launch reflects a broader shift toward edge-based AI, where intelligence increasingly lives directly on personal devices, enabling faster and more reliable experiences without constant connectivity.
Expanding Access to High-Quality Reading
By moving inference onto the device, Speechify can deliver premium-quality AI voices regardless of data plans or network conditions. This approach supports broader access to high-quality reading experiences, particularly in regions where connectivity is expensive, inconsistent, or unavailable.
Speechify On-Device iOS Voices are powered in part by Apple’s Core ML framework, enabling efficient local performance on iOS while maintaining voice quality and responsiveness.
Built for Choice and Reliability
With the introduction of Speechify On-Device iOS Voices, users now have greater flexibility in how they experience AI-powered reading. Users can choose between cloud-based voices or on-device playback depending on their environment, preferences, and connectivity needs.
On-Device iOS Voices reinforces Speechify’s commitment to making reading fast, reliable, and accessible wherever people choose to listen.
