TTS text to speech.
TTS (TXT) synthesizes speech from string TXT, and speaks it. The audio format is mono, 16 bit, 16k Hz by default.

WAV = TTS(TXT) does not vocalize but output to the variable WAV.

TTS(TXT,VOICE) uses the specific voice. Use TTS('','List') to see a list of availble voices. Default is the first voice.

TTS(...,PACE) set the pace of speech to PACE. PACE ranges from -10 (slowest) to 10 (fastest). Default 0.

TTS(...,FS) set the sampling rate of the speech to FS kHz. FS must be one of the following: 8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000. Default 16.

This function requires the Mirosoft Win32 Speech API (SAPI).

% Speak the text;
tts('I can speak.');
% List availble voices;
tts('I can speak.','List');
% Do not speak out, store the speech in a variable;
w = tts('I can speak.',[],-4,44100);

For text to speech app, use "Text speaker". I use it to listen to my text documents. The natural, human sounding voices are excellent. It's easy to create mp3 audio file from the text.

when using this function to read a long text is there a way to interrupt it so that it doesn't continue reading all the remaining text?

Ho to add new language to list ??? I need to get polish languages.


Excellent, thank you, works perfectly. Here is the code I used to create a nice compressed .ogg audio file:

% List availble voices;
tts('I can speak.','List');
% Use one of the voices from the list
w = tts('1, 2, 3, 4, 5','Microsoft Zira Desktop - English (United States)',0,44100);
% Save the data as a compressed .ogg audio file
