This anthropomorphized wood bowl will read Tweets out loud. It was built by [William Lindmeier] as part of his graduate work in the Interactive Telecommunications Program (ITP) at New York University. View the clip after the break to see and hear a list from his Twitter feed read in rather pleasant text-to-speech voices.
The electronics involved are rather convoluted. Inside the upturned bowl you’ll find both an Arduino and a Raspberry Pi. But that’s not the only thing that goes into this. The best sounding text-to-speech program [William] could find was for OSX, so there is a remote computer involved as well. But we think what makes this special is the concept and execution, not the level of hardware inefficiency.
The knob to the left sets the volume and is also responsible for powering down the device. The knob of the right lets you select from various Twitter lists. Each turn of the knob is responded to with a different LED color in the nose and a spoken menu label. You can get a quick overview of the project from this summary post.
This unassuming little board can give your project the power of speech! Parallax’s new Emic 2 Text-to-Speech Module (now available in the Maker Shed) is an easy to use speech synthesis board capable of speaking both English and Spanish. You simply pass it text or numbers over serial and it converts them into a natural sounding voice. Project possibilities include talking GPS units, clocks, thermometers, timers, or giving your robot a voice. You can even have it read your e-mail or twitter feeds! It’s easy to hook up to an Arduino, runs on 5V, and only uses up two data pins for serial communication. Just plug in a speaker and you’ll have your projects talking in no time.
Features:
- High-quality speech synthesis for English and Spanish languages
- Nine pre-defined voice styles comprising male, female, and child
- Dynamic control of speech and voice characteristics, including pitch, speaking rate, and word emphasis
- Industry-standard DECtalk text-to-speech synthesizer engine (5.0.E1)
This is the EMIC2 text-to-speech module. You can see from the logo on the bottom left it’s the latest gadget coming out of [Joe Grand's] Grand Idea Studios. [Dino] tipped us off about his first experience with a prototype of the board. He’s driving it with an Arduino and the video after the break shows that the sound rendering is high quality and the words are very easy to understand. One of the things that we think is interesting is that the serial communications used to drive the board are not uni-directional. In fact, there’s a serial terminal that provides documentation on how to use the chip. Obviously this is most suited to the Arduino, which always has a PC-side terminal window available to it.
[Joe] himself shows some of the potential for the board. He gave new life to a broken toy by replacing its internals with a PIC-based circuit to drive the EMIC2. That video is also found after the break. He’s just using the demo clips, but from that you will get a good idea of the vocal modulations this device is capable of. The board rings up at $60 and is available from Parallax.
