Pitch marking is very significant in speech signal processing. In a text-to-speech (TTS) system based on the Time-Domain Pitch-Synchronous Overlap-Add (TD-PSOLA) method, robust estimation of pitch marks (PM) is especially important to the modification of the time and pitch scale of a speech signal in order to match it to that of the target speaker. The aim of this paper is to improve the accura...

A novel Statistical Approach for F0 Estimation, SAFE, is proposed to improve the accuracy of F0 tracking under both clean and additive noise conditions. Prominent Signal-to-Noise Ratio (SNR) peaks in speech spectra are robust information source from which F0 can be inferred. A probabilistic framework is proposed to model the effect of additive noise on voiced speech spectra. It is observed that...

In this paper we present a new formant tracking algorithm where the formant frequencies estimation was based on local maxima detection of a time frequency representation. This representation can be shown by a scalogram issued from a complex wavelet transform. The formant frequency candidates are validated as local maxima of scalogram which correspond to wavelet ridges. Then in the proposed algo...

The role of speech coding is to reduce the bit rate by maintaining good speech quality. In order to improve the perceptual quality of degraded speech, different speech enhancement methods can be used. So, it is worthwhile to do research in joint systems (Speech Enhancement and Low bit rate speech coders). The work reported in this paper shows the improvement in the perceptual quality of speech ...

. This paper describes a tool designed to allow linguists to manipulate the prosody of an utterance via a symbolic representation in order to evaluate linguistic models. Prosody is manipulated via a Praat TextGrid which allows the user to modify the rhythm and melody. Rhythm is manipulated by factoring segmental duration into three components: (i) intrinsic duration determined by phonemic ident...

In this study, we analyse a sample of 76 utterances drawn from corpus spontaneous speech the north England. The selected statements present declarative structure with different pragmatic functions (yes/no questions, echo tag and rhetorical questions). objective study is to observe describe intonation questions in English England speech. Likewise, pertinent bibliographic review carried out for i...

ABSTRAK: Tujuan penelitian ini dilakukan adalah untuk mengidentifikasi bunyi ujaran kalimat imperatif,kalimat ekslamatif dan berita dalam bahasa Batak Angkola. Penelitian dengan menggunakan Praat mengukur parameter akustik kajian fonetik seperti frekuensi ,durasi, intensitas . Pengukuran eksperimental sinyal yang diekstrak analisis spektrum bantuan komputer software ada di bernama Praat.Hasil r...

Due to the difficulties of speech signal processing, there is still a considerable gap between ability machines correctly process and that human beings. In order overcome defects isolated learning noise sensitivity SOM, this paper proposes new time self-organization model (TSOM) from perspective deep learning. On basis self-organizing mapping network, enhancement mechanism introduced improve sy...

El presente artículo analiza las características fonéticas de los inmigrantes polacos en su pronunciación consonantes. La investigación se ha realizado a partir encuestas recogidas una muestra población polaca adulta y no bilingüe residente España durante más 10 años. trabajo presenta la descripción comparación fonética acústica (a través del análisis mediante el programa informático PRAAT) con...

The use of special intonation patterns, interrogative particles, the addition tags, disjunctive structures, a change in order constituents, and particularly verbal inflection are among strategies for forming polar questions. This paper describes pattern, tags tandem with question particles conjunction pattern to form questions Lɛtɛ. further discusses social norms governing interrogatives Lɛtɛ d...
