This is my first attempt to write an app for the Maemo platform, hope it works for you and won't break anything of your Nokia device . Features of this app are listed below:

• A Hildon/Gtk+ GUI client written in Python for eSpeak, the open source command-line text-to-speech tool.
• Selection of 49 languages, including voice packs that are still in experimental status (default English)
• Amplitude (0 to 199, default 100) adjustment.
• Pitch (0 to 99, default 50) adjustment.
• Speed (words per minute, 80-390, default 170) adjustment.
• Word Gap (in milliseconds, 0-20, default 10) adjustment.
• Opening a text file and loading its contents to the text box for editing and speaking.
• Direct pasting text contents to the text box for editing and speaking (no need to press Ctrl-V)
• One-click-clearing text contents of the text box
• Saving the speech to a .Wav file.
• Speak multiple sentences simultaneously new
• Stop speaking at any time new
• Toggling between Full Screen / Window mode.
• Portrait Mode Support (experimental).
• Saving the language/amplitude/pitch/speed/word gap selection when program exits, and loads them back when program launches automatically.
• Supports multi-language user interfaces based on the Device Language selected. (Traditional Chinese, Simplified Chinese and English UIs will be provided initially)

You can now download this app from maemo extras-devel repository.

This app is a very rough one and it will take some time to fix the major issues before it can be practically usable. Feel free to report issues and suggest enhancements that you would like to have
