Text to Speech on Nokia E90

Let your phone talk! Let your phone read your messages out loud with Text-to-speech! When you drive a car, its dangerous to read incoming message on your E90. I don’t know if this allowed or not, but “hearing” message is much more saver than read it for me.

Text-to-speech (TTS) is a tool which allows you to listen to text messages, multimedia messages, and emails. To utilize your Message Reader application, the only thing you need is download language packages and voice packages.

One of the best things about this algorithm is its modular concept. This means that its packets can be downloaded separately from main software. There is several language packs shipped in the sales package. As a rule, such files with voice packs are stored on memory card. TTS available in following languages:

UK English
Bahasa indonesia
Indian English
Simplified Chinese
Traditional Chinese
Brazilian Portuguese
Latin American Spanish
Canadian French
US English

Each language pack is about 1.86mb big. As you have guessed, there can be several voices for every language, for example, a male voice, or female or childish (it’s not a trivial case for realization, as it may seem at first sight). This means that user will be able to choose the voice that will cast messages or exercises. A pretty neat addition that makes TTS functionality even bigger.

As for additional voice settings, you can select volume and speed. Speed can be adjusted from 1 to 10, in this case 1 will be very slow and 10 will remind you of a tongue-twister, as a result you will not be able to comprehend it at all.
Speaker-independent voice-dialing is quite good - you can dial any number from the phone book without having to train the phone with voice tags or whatever.
