Speakers vary their speed of speaking according to contextual and physical factors. A typical speaking rate for English is 4 syllables per second, [5] but in different emotional or social contexts the rate may vary, one study reporting a range between 3.3 and 5.9 syl/sec, [6] Another study found significant differences in speaking rate between story-telling and taking part in an interview.
A good example for the SSP in English is the one-syllable word trust: The first consonant in the syllable onset is t, which is a stop, the lowest on the sonority scale; next is r, a liquid which is more sonorous, then we have the vowel u / ʌ / – the sonority peak; next, in the syllable coda, is s, a sibilant, and last is another stop, t.
A sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones).Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, [1] therefore sonority is often related to rankings for phones to their amplitude. [2]
Phonotactics (from Ancient Greek phōnḗ 'voice, sound' and taktikós 'having to do with arranging') [1] is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes. Phonotactics defines permissible syllable structure, consonant clusters and vowel sequences by means of phonotactic constraints.
Bounded vs. unbounded: In a bounded language the main stress appears a fixed distance from the word boundary and the secondary stress appears at fixed intervals from other stressed syllables. In an unbounded language the main stress is drawn to 'heavy' syllables (syllables with long vowels and/or consonants at the end of the syllable).
Acoustic phonetics is a subfield of phonetics, which deals with acoustic aspects of speech sounds. Acoustic phonetics investigates time domain features such as the mean squared amplitude of a waveform, its duration, its fundamental frequency, or frequency domain features such as the frequency spectrum, or even combined spectrotemporal features and the relationship of these properties to other ...
Sound sources refer to the conversion of aerodynamic energy into acoustic energy. There are two main types of sound sources in the articulatory system: periodic (or more precisely semi-periodic) and aperiodic. A periodic sound source is vocal fold vibration produced at the glottis found in vowels and voiced consonants.
