Phoneme
The user can use the rotary to choose a group to play: Vowels/Voiced/Voiced Stop/Voiceless/All Allophone/All Effects/DTMF
Using the switch position to set the priority to:
- the gate signal. The gate going high will trigger the speech and it will be stopped with the gate going low (Gate mode). try to play with the duty cycle of the gate or the clock signal.
- optimized transitioning (Queue mode). Play with the Speed function to fill up the buffer and ear the transition work. The green led and the AUX jack will turn on and off reflecting the buffer half-full status.
- to the allophone timing itself (Speech mode)
Number
There are three modes to generate numbers: CV controlled, Looping or Random.
SD DIC
The code will read a phonetic file and allow the user (or the code in the loop and random mode) to choose a line from that file.
Example of the file content:
along: \UX \LO \OH \OH \SLOW \NGO alpha: \AY \LE \FAST \FF \UX alphabet: \AY \LO \FAST \FF \FAST \AX \STRESS \SOFT \BE \EY \SLOW \TT already: \AW \LE \FAST \RR \EY \DE \IY also: \SLOW \AW \SLOW \LO \SLOW \SO \OWWW although: \FAST \OH \SLOW \LO \DH \SLOW \OWWW always: \SLOW \AW \LE \WW \EYIY \SLOW \SE
User control
The potentiometer P1-P5 affects the pitch, rate, bend, repeat, and volume.
While playing with the interface, the display contextually shows the information about the changes made (rotary, switch, and potentiometers)
