SPEECH

MECHANICAL

CONNECTED

Mrs. Hind Al-Beladi


Why shall we study aspects of connected speech l.jpg

Why shall we study aspects of connected speech?

Oral Speech is a continuous stream of sounds without clear-cut borderlines between each word. In spoken discourse, we adapt our pronunciation to our audience and articulate with maximal economy of movement rather than maximal clarity. Thus, certain words are lost, and certain phonemes linked together as we attempt to get our message across.

Aspects of Connected Speech

  • Weak Forms

  • Rythm

  • Elision

  • Linking

  • Assimilation

  • intonation

Weak forms

1

When we talk about weak forms in the phonetics of English this regards a series of words which have one pronunciation (strong) when isolated, and another (weak) when not stressed within a phrase.

e.g. It is his car v. /əz/

The car is his. /hiz/

Mrs. Hind Al-Beladi


There is a tendency for vowels in unstressed syllables to shift towards the schwa central position l.jpg

There is a tendency for vowels in unstressed syllables to shift towards the schwa (central position)

Mrs. Hind Al-Beladi


Weak form are commonly used words l.jpg

Weak form are commonly used words

  • Prepositions (at)

  • Auxiliary verbs (must)

  • Conjunctions (and)

  • Pronouns (his)

  • Articles (the)

  • Qualfiers (as)

EXAMPLES

Mrs. Hind Al-Beladi


Slide8 l.jpg

Look at this phrase:

I went to the station and booked two tickets for my father and his best friend.

Mrs. Hind Al-Beladi


What are the most important words l.jpg

What are the most important words?

I wentto the stationand booked two ticketsfor my fatherand his bestfriend.

Mrs. Hind Al-Beladi


If we eliminate the other words can we still understand the message l.jpg

If we eliminate the other words can we still understand the message?

went station booked two tickets father best friend.

Mrs. Hind Al-Beladi


Weak unstressed l.jpg

Weak=unstressed

In the following sentences the underlined words are stressed and so would be pronounced using the strong form:

I do like chocolate.

She drove to Las Vegas, not from Las Vegas.

We were surprised when she told us her secret.

(stress on ‘were’ for emphasis)

Assimilation

Mrs. Hind Al-Beladi


What is assimilation l.jpg

What is assimilation?

A phoneme might be released according to the effect of neighboring words. In other words, a phoneme may be realized differently as a result of being near some other phoneme belonging to a neighboring word we call this an instance of assimilation.

Mrs. Hind Al-Beladi


Definition l.jpg

Definition:

Assimilation is a common phonological process by which the phonetics of a speech segment becomes more like that of another segment in a word (or at a word boundary).

Example:

A common example of assimilation would be "don't be silly" where the /n/ and /t/ in "don't" become /m/ and /b/= ("dom be silly").

Mrs. Hind Al-Beladi


Where does assimilation appear l.jpg

Where does assimilation appear?

Assimilation is more likely to be found in rapid, casual speech and less likely in slow, careful speech.

Mrs. Hind Al-Beladi


Slide16 l.jpg

  • consider case where two words are combined, the first of which ends with a single final constant ( which we will call C ) and the second of which starts with a single initial consonant ( which we will call C ); we can construct a diagram like this:

    ………….Cf | Ci……….

    |=the word boundary

Slide17 l.jpg

TYPES OF ASSIMILATION

Mrs. Hind Al-Beladi


Slide18 l.jpg

  • If Cf changes to become like Ci in some way, then the assimilation is called regressive (the phoneme that comes first is affected by the one that comes after it); if Ci changes to become like Cf in some way, then the assimilation is called progressive.

Mrs. Hind Al-Beladi


Slide19 l.jpg

The main differences between

consonants are of three types:

1) differences in place of articulation;

2) difference in manner of articulation;

3) differences in voicing.

Mrs. Hind Al-Beladi


Assimilation of place l.jpg

Assimilation of Place

The most common form involves the movement of place of articulation of the alveolar stops /t/, /d/ and /n/ to a position closer to that of the following sound (WHICH IS NOT ALVEOLAR).

Mrs. Hind Al-Beladi


Assimilation of place21 l.jpg

Assimilation of Place

  • For instance, in the phrase ten cars, the /n/ will usually be articulated in a velar position, /teN ka:z/ so that the tongue will beready to produce the following velar sound /k/.

  • Similarly, in ten boys the /n/ will be produced in a bilabial position, /tem boIz/to prepare for the articulation of the bilabial /b/.

Elision

3

Elision is very simply the omission of certain sounds in certain contexts. In certain circumstances a phoneme may be released as ZERO, or have ZERO REALIZATION or be DELETED. Elision is typical of rapid, casual speech. The most important occurrences of this phenomenon regard:

1Alveolar consonants /t/ and /d/ when ‘sandwiched’ between two consonants (CONS – t/d – CONS), e.g.

Elision of not l.jpg

Elision of ‘not’

The phoneme /t/ is a fundamental part of the negative particle not. Consider the negative of can – if followed by a consonant the /t/ may easily disappear and the only difference between the positive and the negative is a different, longer vowel sound in the second:

+I can speak…./ai kən spi:k/

- I can’t speak…/ai ka:nspi:k/

Intonation

4

  • IT IS the rise and fall of the pitch of sound in speaking.

  • The function of intonation is to express attitude, feeling or emotion
