• 06.03.11 Vowel and speech synthesis (Speech)

  • Vowel and speech synthesis Oscillator Model
    • 
  • Description: The Speech oscillator draws on speech synthesis research begun by Texas Instruments in the late 1970s, which led to the Speak & Spell talking toy. Vowels use unrestricted airflow while the throat and tongue shape their sound; consonants delimit and shape vowels.
  • Microfreak/UI/Oscillator/Knob/Type/Speech/Type
    • The Microfreak/UI/Oscillator/Knob/Wave knob scans
      • 1 - formants from 0 to about 100,
      • 2 - then libraries of colors,
      • 3 - numbers,
      • 4 - letters, and
      • 5 - words.
  • Microfreak/UI/Oscillator/Knob/Type/Speech/Timbre:
    • Shifts the speech formants up or down.
  • Microfreak/UI/Oscillator/Knob/Type/Speech/Word:
    • The Microfreak/UI/Oscillator/Knob/Shape knob scans subsets of words from the library selected with the Wave knob.

  • Examples

    • Set Wave to its maximum, Timbre to 40, and Shape to 30. Play middle C to hear “Filter.” Enable paraphony to play the word with four voices.
    • Set Wave to 60, Timbre to 46, and Shape to 17. Play middle C to hear “One.”

  • Singing count

    • Activate Arpeggio mode with Arp|Seq.
    • Assign the oscillator Shape parameter to the LFO by pressing Assign 1 and turning Shape.
    • Set the modulation amount to about 80.
    • Select the triangle wave on the LFO and set its speed to about 80 Hz.
