voice

voice — An emulation of a human voice.

Description

An emulation of a human voice.

Syntax

ares voice kamp, kfreq, kphoneme, kform, kvibf, kvamp, ifn, ivfn

Initialization

ifn, ivfn -- two table numbers containing the carrier waveform and the vibrato waveform. The files impuls20.aiff, ahh.aiff, eee.aiff, or ooo.aiff are suitable for the first of these, and a sine wave for the second. These files are available from ftp://ftp.cs.bath.ac.uk/pub/dream/documentation/sounds/modelling/.

Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played. It can be varied in performance.

kphoneme -- an integer in the range 0 to 16, which select the formants for the sounds:

  • eee, ihh, ehh, aaa,

  • ahh, aww, ohh, uhh,

  • uuu, ooo, rrr, lll,

  • mmm, nnn, nng, ngg.

At present the phonemes

  • fff, sss, thh, shh,

  • xxx, hee, hoo, hah,

  • bbb, ddd, jjj, ggg,

  • vvv, zzz, thz, zhh

are not available (!)

kform -- Gain on the phoneme. values 0.0 to 1.2 recommended.

kvibf -- frequency of vibrato in Hertz. Suggested range is 0 to 12

kvamp -- amplitude of the vibrato

Examples

Here is an example of the voice opcode. It uses the file voice.csd, and impuls20.aiff.
