CHATR Utterance Modules

These commands take a single utterance as an argument and process it in their own way. For all practical purposes they are the same as CHATR commands, but were separated as this is the more likely form of function general users will define.

Contour_Values

Print out absolute amplitude of events.

Duration

Set segment durations using type of duration module selected.

Feature_Int

Process intonation prior to Rfc_Module.

Feature_to_Num

Convert feature list in intone stream to numerical value scores, using the information as defined in the intonation statistics.

HLP

Apply phrasal boundary information tune assignation, based on HLP rules. Create the Pphrase and Word streams.

Input

Read input stream and put information into the appropriate stream. A pre-requisite for many functions.

Intonation

Align intones to syllables.

Int_target

Generate target points from intone stream using appropriate intonation theory.

Lexicon_Module

Look up words in lexicon and build syllable and phoneme streams.

Linear_to_Z

Convert linear values in intone stream to z scores, using the mean and standard deviation information as defined in the intonation statistics.

LP

Perform linguistic processing after Input function has been called. No waveform synthesis is performed.

Num_to_Feature

Convert values in intone stream from numerical format to values in feature format.

Phonology

Map phonemes to segments. Fill phoneme information and pauses.

Phrasify

Make phrase stream from syllable and segment stream.

Rfc_Module

Create RFC stream from Intone stream, and generate F0 targets in segment stream.

Rfc_to_Tilt

Convert values in Intone stream from "RFC" specified values to values in "tilt" space.

Syllabify

Make syllable stream from segment stream.

Synthesis

Generate a waveform for the given utterance using the synthesis method set by (Parameter Synth_Method X). Then run the functions in synth_hook on the utterance after the waveform is built.

Unit_Modify_Cutpoints

Modify the existing unit stream start and end points for `best' place to cut, based on cepstrum distance.

Tilt_to_Rfc

Convert values in Intone stream from "tilt" specified values to values in "RFC" space.

Unit_Concat

Concatenate loaded units using desired concatination method.

Load_Hand_Units

Load the unit stream with hand specified units.

Word

Add boundary information to words and build intone stream. Also call the lexicon which builds syllable and phoneme streams.

Z_to_Linear

Convert z score values in intone stream to linear, using the mean and standard deviation information as defined in the intonation statistics.
