Review: The Organs of Speech

The Larynx and the Vocal Folds

Review: Place of Articulation

-Place of Articulation is the location at which two speech organs approach or come together in producing a speech sound.

1. Bilabials : These are sounds formed using both (= bi) upper and lower lips (= labia) -The initial sounds in the words: bat , pat , map , and walk are all bilabials.

-These sounds are represented by the symbols : [b] , [p] , [m], [w]. 2. labiodentals : These are sounds formed with the upper teeth and the lower lip.

-The initial sounds of the words fat , vat are labiodentals.

-These sounds are represented by the symbols: [f], [v].

3. Dentals : These sounds are formed with the tongue tip behind the upper front teeth. - The initial sounds in the words: three and then are dentals. -These sounds are represented by the symbols: [θ], [ð].

4. Alveolars : These sounds are formed with the front part of the tongue on the alveolar ridge.

The initial sounds in the words : top, dip, sit , zoo, nut, lap and rip.

- These sounds are represented by the symbols: [t], [d], [s], [z], [n], [l], [r].

5. Alveo-palatals : These sounds are produced with the tongue at the very front of the palate, near the alveolar ridge.

- The initial sounds in the words: ship, chip, gem, and the middle consonant sound in words like pleasure are alveo-palatal. - These sounds are represented by the symbols: [ ʃ ], [t ʃ ], [ ʒ ], [d ʒ ].

6. Palatals : One sound which is produced with the tongue in the middle of the palate is the [j] sound to be found at the beginning of words like you and yet.

7. Velars : These sounds are produced with the back of the tongue against the velum ( the soft palate) .

- The initial sounds in the words: kid, gig and the middle consonant sound in words like English are velars. - These sounds are represented by the symbols: [k], [g], [ŋ].

8. Glottals : There is one sound that is produced without the active use of the tongue and other parts of the mouth. It is the sound [h].

- The sound [h] is produced with the air passing through the opening between the separated vocal folds. This opening is called the glottis. - The sound [ h] occurs at the beginning of words like house and have.

Manner of Articulation

- Manner of articulation describes how the tongue, lips, jaw, and other speech organs are involved in making a sound.

- The concept is often only used for the production of consonants.

Today, we’ll learn about a third way to describe sounds: their manner of articulation -[d], [n], and [z] are all voiced alveolar sounds - What makes them different sounds? -Their manner of articulation is different.

1. [d] is a stop (complete closure) 2. [z] is a fricative (incomplete closure) 3. [n] is a nasal (Airstream is allowed to flow out through the nose)

-Manner of articulation: the various configurations produced by positioning the lips, tongue, velum, and glottis in different ways.

★ ★ ★ ★ ★ ★ Oral vs. Nasal Stops Fricatives Affricates Liquids Glides Approximants

Oral vs. Nasal

❖ The velum: soft part at the back of the mouth behind the uvula.

❖ The velum can be raised and lowered.

★ When raised: blocks airflow through the nasal passage (the nose) ➙ oral sounds ★ When lowered: air flows through the nasal passage ➙ nasal sounds

- Look at the animations of [p] and [m] on the UIowa Phonetics Website.

❖ Nasal consonants in English: [m]: bilabial nasal, as in map [n]: alveolar nasal, as in nap [ŋ]: velar nasal, as in sang

Stops

❖ Stops: consonants made with a complete closure either in the oral cavity or in the glottis. ★ English stops: bilabial, alveolar, velar, glottal ❖ Try holding the sounds [p], [t] and [k]: what happens to the airflow?

1. Oral stops : complete closure in the oral cavity and the velum is raised.

★ Oral stops: [p, t, k, b, d, g] 2. Glottal stop : [ ʔ ] complete closure in the glottis.

★ Always voiceless 3. Nasal stops : complete closure in the oral cavity, but the velum is raised. Air escapes through the nasal passage.

★ Nasal stops: [m, n, ŋ] ★ More sonorous than other stops (louder, more intense): airflow is not as restricted. ★ Always voiced

❖ Look at the animations of stops on the UIowa Phonetics Website.
