frequency count. This involves collecting a speech sample from the client, ascertaining the number of syllables or words spoken within the sample and then calculating the number of syllables or words which are stuttered. This figure is most commonly expressed as a percentage of stuttered syllables, or stuttered words (%SS; %WS) and usually accom¬panied by an analysis of speech rate expressed in the number of syllables or words spoken per minute (SPM, WPM). Figure 9.1 shows how speech fluency and speech rate can be calculated in this way. Counting stuttered syllables and rate in this manner is a well-established procedure and a supposed objective way of collecting data on the severity of stuttering. As we will see a little later in this section, however, there are a number of weaknesses and potential problems with this procedure. (See also Lees, 1994 for a critique of the syllable count.)
The fluency count
The fluency count is most commonly used as part of the information gather¬ing process at assessment and at post-clinic and follow-up sessions, although it may be used throughout the therapeutic process to continuously monitor the client’s progress (as is often the case on fluency shaping programs; see chapter 12). Most clinicians advocate that the speech sample comprises a minimum of two minutes of the clients talking time, excluding pauses. To accurately analyze the time taken during speaking, the talking time must be calculated using a stopwatch, which should be stopped when the client is either listening or considering a reply, as well as during pauses, but not where there is silence due to stuttering (for example, during a silent block). Simul¬taneously, the clinician must count each syllable whilst also making note of syllables which are stuttered upon. To do this accurately and reliably involves a number of skills. First, the clinician must be adept at counting syllables accurately at what may be a fast rate, whilst being able to recognize which of those syllables are stuttered. To this end, criteria as to what does and does not
