¶ Preparatory Steps
- Create script.
- Select Audio mode → Audio recordings in the starting-block settings under Speech.
- Select an appropriate voice for speech synthesis in the Voice Type field.
Variables and texts in blocks that do not have audio files attached will be voiced by speech synthesis. Therefore, it is important that the Voice for synthesis should be as similar as possible to the voice of the speaker in the audio recording, and the text should be free of spelling errors. If you use words in a foreign language - provide their transcription.
- Click the Uploading all texts button in the start block settings to unload phrases from the script blocks.
- Record audio with the phrases from the script. Refer to Voicing for recording guidelines.
