Parallax Emic 2 text-to-speech module

Posted on Wednesday, July 4th, 2012 in new parts by the machinegeek

Parallax has released their Emic 2 Text-to-Speech Module. The Emic 2 is a multi-language voice synthesizer that converts a stream of digital text into natural sounding speech. The module requires a 5 volt DC power supply at 30 mA, and interfaces with your project via 9600 baud asynchronous serial (TTL).

The module is capable of producing 9 different voices in both English and Spanish using the Fonix DECtalk speech syntheizer engine. The commands (described in the product brief) allow dynamic control of speech and voice characteristics, including pitch, speaking rate, and word emphasis. The on-board audio amp allows for direct connection to an 8-ohm speaker using the SP+ and SP- pins.

More details follow.

Emic 2 was produced in cooperation with tech guru Joe Grand of GrandIdeaStudio. (For videos about the development and use of the Emic2, visit Joe’s KingpinEmpire video page.)

    As a random piece of trivia, Stephen Hawking uses a 1988 version of DECTalk.
    He uses the voicing known as “Paul” which is one of the voices implemented by this module.
