7.1 How It All Works

Here is a brief explanation of the connection between `voice-bolden' and its associated `voice-bolden-settings'.

1. Voice settings are initially in `voice-bolden-settings' which is a list of numbers.
2. That list of numbers needs to be translated to appropriate device-specific codes to send to the TTS engine.
3. You do not want to do this translation each time you speak something.
4. So when `voice-bolden' is defined, the definition happens in two steps:

• The list of settings is stored away in `voice-bolden-settings',
• A corresponding voice-name is generated — `acss-a<n>-p<n>-r<n>-s<n>' and the corresponding control codes to send to the device are stored away in a hash-table keyed by the above symbol.
• Finally, `voice-bolden' is assigned the above symbol.

• What this gives.
