The ordinary TTS speed rates are 80, 100, and 150. In my quest to become a speed hearer, I've had to create a launchpad-script with which you can change the rate beyond these.
Sequence
Shift S X decrements the speed rate with 25.
Sequence
Shift S C increments the speed rate with 25.
Sequence
Shift S V updates the speed rate to a predetermined one, with the default value 220.
Place the script in the Launchpad folder and press the sequence Shift Shift Space to refresh Launchpad. It works for me with firmware 3.2.1 on Kindle 3.
Note that TTS must be enabled when using the script and that the speed rate will be returned to the menu setting when restarted.
PHP Code:
[Actions]
S X = !INCREMENT=-25; OLDSPEED=`lipc-get-prop com.lab126.tts TtsISpeed`; NEWSPEED=$(($OLDSPEED+$INCREMENT)); `lipc-set-prop com.lab126.tts TtsISpeed $NEWSPEED`
S C = !INCREMENT=25; OLDSPEED=`lipc-get-prop com.lab126.tts TtsISpeed`; NEWSPEED=$(($OLDSPEED+$INCREMENT)); `lipc-set-prop com.lab126.tts TtsISpeed $NEWSPEED`
S V = !NEWSPEED=220; `lipc-set-prop com.lab126.tts TtsISpeed $NEWSPEED`
Feel free to use it however you wish and please criticize.
