speak
Speak a string.
Syntax
speak(str) speak(str, opt)
Description
speak(str) speaks string str, using the default system settings.
speak(str,opt) uses the speech options in opt.
speak returns as soon as possible, without waiting until the text has been uttered. Function isspeaking checks if the last speak call is completed. If speak is called before the previous call is completed, it waits, so that continuous speech is produced.
Speech options are set with speakset or with named arguments.
Example
speak('Hello, L M E !')

speakset
Options for speech synthesis.
Syntax
options = speakset options = speakset(name1, value1, ...) options = speakset(options0, name1, value1, ...)
Description
speakset(name1,value1,...) creates the option argument used by speak. Options are specified with name/value pairs, where the name is a string which must match exactly the names in the table below. Case is significant. Options which are not specified have a default value. The result is a structure whose fields correspond to each option. Without any input argument, speakset creates a structure with all the default options. Note that speak also interprets the lack of an option argument, or the empty array [], as a request to use the default values.
When its first input argument is a structure, speakset adds or changes fields which correspond to the name/value pairs which follow.
Here is the list of options. Some of them are not available on all platforms; type speakset without argument to verify. Experimenting is the best way to find the values you prefer.
| Name | Meaning |
|---|---|
| Pitch | voice pitch (frequency, only on Mac) |
| Rate | rate (words per minute, only on Mac) |
| RateAdjustment | rate adjustment between -10 and 10 (only on Windows) |
| Voice | name of the voice (empty string=default) |
The list of voices available on your computer can be obtained with speakvoices.
Example
Default options on Mac:
speakset Pitch: 5.8763 Rate: 201 Voice: ''
