5 Features of Connected Speech

 Written by Keith Taylor

A look at assimilation, elision, delayed plosion, catenation and intrusion in


connected speech.
In spoken discourse the boundaries between words are very often not clear-
cut. Words and sounds are lost and linked together in different ways to
enable us to articulate with minimal movement.

This is one of the reasons learners find spoken discourse more difficult to
understand than written discourse. At higher levels it is often not a lack of
vocabulary which prevents understanding, but lack of ability to deal with
these features of connected speech. Native speakers are more able to
use top-down processing to decide whether what they have heard is red
dye or red eye.

Here are some of the more common features of connected speech:

1.Assimilation
Assimilation occurs when a phoneme (sound) in one word causes a
change in a sound in a neighbouring word. For example, try saying
the following pairs of words:

 in Bath
 last year
 Hyde Park
You’ll notice that the last sound of the first word changes in each
case. The /n/ sound
becomes /m/, /t/ becomes /tʃ/ and /d/ becomes /b/.

2.Elision
Elision is the loss of a phoneme, most commonly the last phoneme
of a word, and most commonly the /t/ and /d/ sounds. Have a look
at these examples:
 left back
 stand by
 looked back
 I must go
In each case the last phoneme of the first word is elided (lost). In
the most simple terms, the reason is that the time and effort
required to change the mouth position from the /t/ to the /b/ sound
(as in the first example) or the /t/ to the /g/ sound (as in the last
example) is too great!

3.Delayed plosion
Our “red dye” and “red eye” is an example of this. To articulate “red
dye”, we must take a very short pause before the /d/ sound.
The /d/ is an example of a plosive, consonant sounds where the
vocal tract stops all airflow. Other examples
are /b/,/d/, /g/, /p/, /t/ and /k/. This pause before the plosive gives us
the name of this feature, delayed plosion.

Another example: the right tie (delay) – the right eye (no delay)

4.Catenation
In catenation the last consonant of the first word is joined to the
vowel sound at the start of the second word. For example:

 pick it up – (learners will hear something like pi ki tup)


 what is it – (learners will hear something like wo ti zit)

5.Intrusion
Intrusion is what you might expect from the name – an extra sound
“intrudes” into the spoken utternace. Try saying the following pairs
of words:

 media event
 I always
 go away
Do you hear the /r/ sound intruding after “media”, the /j/ sound
intruding after “I” and the /w/ sound intruding after “go”?
