Example of the use of pauses in numerical strings:

The number is, 1 (800) 5 5 5, 1 2 3 4. [:rate 120]

That is, [_<300>] 1 (800), [_<500>] 5 5 5,

[_<900>] 1 2 3 4. [:ra 180].

The spaces between the numbers ensure that "five five five" is spoken rather than "five hundred fifty five." You can also use the [:mode spell on] command to produce the same results. The slower speaking rate, [:rate 120], and the silence phonemes, [_<300>], [_<500>], [_<900>], of specified durations, were carefully selected to allow enough time for the listener to write down the entire number. Silence phonemes were positioned after the commas (that is, [_<300>] 1 (800), [_<500>]), to maintain appropriate intonation.

As another example, if your application is required to speak sums of money (such as bank balances or item costs), you might code the text to say:

Your balance is $244.05. That is, 2 4 4, [_<400>] point 0 5, [_<400>] dollars.
