      ExpressionNameDescriptionDefault Support*
      PITDPitch CurveControls the pitch curve✅
      DYNDynamics CurveControls the volume of the phoneme✅
      GENCGender CurveThe default range of -100 to +100 is equivalent to shifting the formant by +12 to -12 semitones.❌
      VELCVelocity CurveControls the velocity of the phoneme❌
      ENEEnergy CurveThis expression manipulates the energy of the voice, including the manipulation of vocal intensity.❌
      BRECBreathiness CurveThis expression manipulates the air in the voice; a higher curve increases the air, while a lower curve decreases the air.❌
      TENCTension CurveThis expression affects the tension of the voice, for example, manipulating the power and nasality.❌
      VOICVoicing CurveThis expression affects the amount of sonority, i.e., manipulates the amount of sonority present in the voice. Similar to the energy curve, it is considered a "successor".❌
      PEXPExpressiveness CurveThis expression manipulates the degree of expressiveness of the rendered pitch. The default value is 100 (maximum).❌
      SHFCPitch Shift CurveThis parameter can assign voices from other vocal registers to a different vocal register (for example, the falsetto register to a lower note) to manipulate the voice sound. It can also be used to manually increase the vocal register of the voice. A vocoder that supports this parameter is required.❌
      Voice Color**Voice Color CurveAllows gradual transitions between different voice timbres, similar to the vocal modes of Synthesizer V or XSY of VOCALOID4.❌

      * Expressions without default support require the model being used to have the additional parameters trained.
      ** Expression available only in models that contain more than one trained color.
