How to adjust the pitch (tone)

The pitch parameter controls the tone of the synthesized speech by making the voice deeper or sharper.

It is optional, and if omitted, the default value 0.0 (neutral pitch) is used.

Range: -0.75 (deeper voice) to 0.75 (sharper voice)
Default: 0.0 (neutral pitch)

Use this to make the voice sound either lower or higher depending on your preference or use case.
