How to use the Speech Synthesis Settings robot skill

Use this robot skill to adjust the speech settings and audio effects for spoken speech synthesis on EZB index #0.


Main Window



1. Voice Drop-down
This drop-down contains a selection of installed voices.

2. Emphasis Drop-down
This drop-down contains a selection of speech emphasis levels.

3. Rate Drop-down
This drop-down contains a selection of speeds for the emphasis of speech. Do note that the "Rate" will have no effect unless "Emphasis" is configured to "Not set."

4. Volume Slider
This slider sets the volume percentage for the text-to-speech output (1-100% range).

5. Speed Effect
This uses a bit stretching algorithm to resample the audio speech, which can speed or slow it down. Using this provides some neat effects. A value of 50, for example, will be half of the original speed. A value of 100 is the original speed. A value higher than 100 will increase the speed.

5. Effects
The effects section has several built-in effects for the audio speech. Some products will alter the pitch, add delay, or even add flanger.

6. Copy Values To Script
Creates a script of ControlCommand for every effect parameter that has been modified. Even though the effect settings are saved with a project, this will give you insight into how to adjust the values programmatically. Pressing this button will copy the generated script to your clipboard.
