Platon – Speaking Scientific Calculator with Adjustable Speech Rate

Description

Platon is a powerful, standalone speaking scientific calculator designed for blind and visually impaired users who need accuracy, speed, and full control over spoken feedback. Unlike app-based solutions or devices dependent on smartphones or computers, Platon works completely independently—ready to use anytime, anywhere.

Its key distinguishing feature is the integrated speech rate adjustment, allowing users to adapt the voice output precisely to their personal listening preferences. The speech rate can be changed instantly, in clearly announced steps, from slower speech for comfortable learning up to very fast speech for efficient, expert use—without interrupting calculations or workflows. This makes Platon especially suitable for both beginners and advanced users.

Platon combines clear, high-quality speech output with a wide range of functions: basic arithmetic, advanced scientific calculations, statistics, unit and currency conversions, and financial calculations. Every key press, entry, and result is spoken aloud, while the tactile keyboard layout ensures confident, eyes-free operation.

With its robust hardware, intuitive menu system, and customizable speech behavior, Platon sets a new standard as a fully autonomous speaking scientific calculator with adjustable speech rate, delivering independence, flexibility, and professional performance in one compact device.
