What it does¶
The ALTextToSpeech module allows the robot to speak. It sends commands to a text-to-speech engine, and authorizes also voice customization. The result of the synthesis is sent to the robot’s loudspeakers.
How it works¶
ALTextToSpeech is based on speech synthesizers - or speech engines.
According to the selected language, a specific engine is used:
|Japanese||microAITalk engine, provided by AI, Inc.||microAITalk engine, provided by AI, Inc.|
Note: the engine used is indicated in the description of the package.
The output audio stream can be modified.
For example, these effects are available:
- pitch shifting effect modifies the initial pitch of the voice,
- double voice effect produces a “delay/echo” effect on the main voice.
Additional parameters are available for microAITalk engine.
