The speech speed adjustment allows control over how fast the voice plays. Typically, you can increase or decrease the speed as needed.

1. Normal Speed ​​(1.0x) : The standard speed of the voice.
2. Speed ​​Up (e.g. 1.5x, 2.0x) : The voice plays faster. This is good for listening to long passages quickly.
3. Speed ​​Down (e.g. 0.5x, 0.75x) : This is good for listening carefully, especially to passages that require deep understanding.
