Classification of DA for unseen utterances is based on a novel derivation rule-dialogue act (DRDA) matrix, which is created by counting the occurrences of each DR in each utterance cluster.
Step I: Perform voice activity detection (VAD): The VAD process that discriminates speech frames from non-speech frames in an utterance is based on two sources: the logarithmic magnitude spectrum (abbreviated as logMS) in Equation (10) and log E in Equation (11).
The aim of copy synthesis is to obtain stimuli that are controlled in order to focus on specific features, but are also natural sounding, as all parameters are based on utterances produced by a single speaker.
All feature values are based on the averaged output of the two sentence utterances, which were repeated recordings of the same sentence.
The decision to place the sequences utterance-finally was based on the assumption that vowels are more likely to be lenited if they are found at the end of an utterance [4] or adjacent to prosodic boundaries [15].
(c) To reduce the computing complexity we also propose an alternative utterance reduction model which is based on a GMM and is simplified from the inversion model.
While rapid prediction approach is based on utterances, that is specific linguistic forms, i.e. words, phrases and sentences, our present proposal specifies action sequence structures in terms of intentional speech acts, each of which can be realised with a range of different utterances (see " Introduction" section).
In our application the recognized utterance will be probably shown to the user so that he/she knows whether the utterance was correctly recognized, and where the feedback is based on.
This work presented the current version of the newGASpeech framework, which is based on GA and performs utterance copy through a process of analysis-by-synthesis.
When a speaker did not signalize the phrases and sentences border with their pronunciation, intonation or pauses, the punctuation was based on the meaning of the utterance.
