How to use speech synthesize from text by VOICEVOX API

1. Launch your VOICEVOX server or application.
2. If you change VOICEVOX server address from default, you have to set VoiceVoxBaseURL.BaseURL.
3. Input text to synthesis speech.
4. Create AudioQuery from text by QueryCreationAPI.
5. Synthesize speech from AudioQuery by SynthesisAPI.
6. Decode synthesized WAV file and play on Unity as you like.

• You can select how to decode WAV file on your project.
• In this sample, I use simple-audio-codec-unity I wrote.

A sample code with UniTask is this.
