Speech, then, is produced by an air stream from the lungs, which goes through the trachea and the oral and nasal cavities. It involves four processes:
Initiation, phonation, oro-nasal process and articulation
.
What are the stages involved in speech production?
Speech production at the peripheral level consists of three stages:
exhalation, phonation, and articulation
(Table 2.1).
What is speech production process?
Speech production is
the process by which thoughts are translated into speech
. This includes the selection of words, the organization of relevant grammatical forms, and then the articulation of the resulting sounds by the motor system using the vocal apparatus.
What are the 4 speech systems?
In humans, there are four main body systems involved in the production of speech.
The respiratory system, laryngeal system, and articulatory systems
are responsible for the physical manifestations of speech, and the nervous system regulates these systems on both the conscious and unconscious levels.
What are the four process of speech production?
The production of a speech sound may be divided into four separate but interrelated processes:
the initiation of the air stream, normally in the lungs; its phonation in the larynx through the operation of the vocal folds; its direction by the velum into either the oral cavity or the nasal cavity (the oro-nasal process
…
What is the most important organ of speech?
The tongue
is the most important articulator of speech. This muscle is extremely strong, as it must move food around in our mouths as we chew.
What is the role of glottis in speech production?
The glottis is the opening between the vocal folds (the rima glottidis). The glottis is
crucial in producing vowels and voiced consonants
.
What part of the brain is responsible for speech production?
In general,
the left hemisphere or side of the brain
is responsible for language and speech. Because of this, it has been called the “dominant” hemisphere. The right hemisphere plays a large part in interpreting visual information and spatial processing.
What organs are involved in speech production?
- The Lungs. …
- The Larynx & the Vocal Folds. …
- The Articulators.
Are voice and speech one and the same thing?
Voice (or vocalization) is the
sound
produced by humans and other vertebrates using the lungs and the vocal folds in the larynx, or voice box. Voice is not always produced as speech, however. Pitch is the highness or lowness of a sound based on the frequency of the sound waves. …
What are the speech process?
Speech processing is
the study of speech signals and the processing methods of signals
. … Aspects of speech processing includes the acquisition, manipulation, storage, transfer and output of speech signals. The input is called speech recognition and the output is called speech synthesis.
What are the main important structures in the production of speech?
The main structures that are important in the production of speech are
the lungs and the respiratory system
, together with the vocal organs shown in Figure 1. The airstream from the lungs passes between the vocal cords, which are two small muscular folds located in the larynx at the top of the windpipe.
What is the mechanism of speech?
What is the definition of speech mechanism? Speech Mechanisms the conventional term for
the system of psycho-physiological prerequisites that enable a human being to make meaningful utterances and to understand another’s speech
.

- Powerful Statement/Phrase.
How do humans produce speech?
Speech is produced
by bringing air from the lungs to the larynx (respiration)
, where the vocal folds may be held open to allow the air to pass through or may vibrate to make a sound (phonation). The airflow from the lungs is then shaped by the articulators in the mouth and nose (articulation).
Why is phonation important in speech?
The larynx functions in phonation by
delicately adjusting the vocal cords to produce the required frequencies for the required length of time
. It is important in the voiceless aspects of speech in a passive sense to ensure that the vocal cords are wide open at the glottis, so that air can easily pass out.
