## 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.
