What about this version: Many speech synthesizers allow users to select from among preset options that control different voice parameters (gender, pitch range, stress, richnes, etc.) as a group. When using these synthesizers, make available the full range of preset options (e.g., "adult male voice", "female child voice", "robot voice", etc.). - Ian Jon Gunderson wrote: > > Charles, > What happens is that the user agent can enumerate a number of voice labels > that are typically made available to users as a list of voice > options.
