Audio Settings

When you click the Audio tab in kttsmgr, the Audio screen appears.


The KDE Text-to-Speech Manager (Audio tab)

1

Select the method of audio output here. If a component is is grayed, either KTTS was compiled without that support for that audio plugin, or KTTS was unable to load the necessary libraries.

2

If GStreamer or aKode is selected for audio output, choose the audio sink method here. If no sinks are listed, you need to install at least one. If ALSA is selected, choose the PCM device here. See the section called “Requirements”.

3

Adjust the speed of talking here. 50% is approximately twice as slow as normal while 200% is approximately twice as fast. You must have the sox utility installed for this setting to work.

4

When this box is checked, KTTS will copy temporary audio files (.wav files) into the indicated folder. Choose any folder on your hard drive you like, but you must have write access to it. This can be useful for creating audio files of speech for other purposes. The files will have names of the form kttsd-J-SS where J is the job number and SS is the sentence number. Existing files with the same name will be deleted. Do not forget to uncheck this box, otherwise your hard drive will fill up!

5

Be sure to click Apply to apply the new settings to the running KTTS system.

Note

There are two ways to adjust the speed of speech in KTTS. Many of the Talkers have a Speed setting in their configuration dialogs, which you can display by clicking Edit on the Talkers screen. This Speed setting on the Audio screen is in addition to the talker speed setting and generally can be used even if the talker does not support a speed setting. For this speed setting to work, you must have the sox utility installed on your system (Debian users: apt-get install sox). Also, this speed setting is ignored when speaking text containing SSML. (See the section called “SSML”)

Note

The list of ALSA devices includes all the ALSA PCM devices and plugins configured in your system. Many of the choices will not work. You must experiment to find a device that works for you. If in doubt, choose default.
