[Emacspeak] Providing a more intuitive way to set dtk-speech-rate

[Parham Doustdar <parham90@xxxxxxxxx>]

Hi,

Maybe I’m missing something here, but setting `dtk-speech-rate’ is not as intuitive as `Mac-default-speech-rate’.

Here is what I tried:

• Using `M-x customize-group <RET> tts <RET>’: found no customizable value here. `dtk-default-speech-rate’ is available here, which made it very easy to set up
• Using defvar: this didn’t work either
• Using `defvar-local’: this did it. I found this in the Emacspeak source code, and not sure if this is the right way to set this value

I think using customise for values like this is very user-friendly, will keep my init files cleaner, and will prevent newcomers from having to dive deep into Emacspeak internals.

Thanks,

Parham
