Subvocalization, or silent speech, is the internal speech typically made when reading; it provides the sound of the word as it is read. [1] [2] This is a natural process when reading, and it helps the mind to access meanings to comprehend and remember what is read, potentially reducing cognitive load.
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as unvoiced ) or voiced.
[5] [6] Another source of information is the vocal tract resonance signals that get transmitted through bone conduction called non-audible murmurs. [ 7 ] They have also been created as a brain–computer interface using brain activity in the motor cortex obtained from intracortical microelectrodes .
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. [1] Linguists who specialize in studying the physical properties of speech are phoneticians.
Reading is the process of taking in the sense or meaning of symbols, often specifically those of a written language, by means of sight or touch. [1] [2] [3] [4]For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation.
Because the speech signal is not linear, there is a problem of segmentation. It is difficult to delimit a stretch of speech signal as belonging to a single perceptual unit. As an example, the acoustic properties of the phoneme /d/ will depend on the production of the following vowel (because of coarticulation).
The following table shows the 24 consonant phonemes found in most dialects of English, plus /x/, whose distribution is more limited. Fortis consonants are always voiceless, aspirated in syllable onset (except in clusters beginning with /s/ or /ʃ/), and sometimes also glottalized to an extent in syllable coda (most likely to occur with /t/, see T-glottalization), while lenis consonants are ...
In many descriptions of English, the following intonation patterns are distinguished: Rising Intonation means the pitch of the voice rises over time. Falling Intonation means that the pitch falls with time. Dipping or Fall-rise Intonation falls and then rises. Peaking or Rise-fall Intonation rises and then falls.
