Acoustic characteristics of consonants in the spectrogram for speech analysis with denture prosthesis

Purpose: The Purpos of the article is to asses the improvement on speech quality analysis with spectrogram by modified maxillary denture. We should gain familiarity with acoustic cue features of consonants with spectrographic representations of sounds. Background: “Speech is a brief, physiologically generated and socially conditioned vibratory impact on the human organism upon the atmosphere”. The sound is characterized by phonation or articulation, or both plus resonances. Results: The acoustic cues for consonants like stop gap, release burst, VOT, Friction noise, Formants transition, formant durations, voice bar and formant frequencies are to be analyse perceptually and objectively. We need to appreciate the differences between narrow-band and wide-band spectrograms, by learning how features of speech sounds appear on spectrograms and how the spectrogram can lead to a quantitative analysis of the source and filter aspects of speech sounds. Conclusion: One of the main aspects of prosthodontic treatment for the management foredentulism depends on acoustic quality of speech. Maxillary palatal surface is significant in producing speech sounds particularly for consonants.
