SIP-CCLP Ver. 4.0 is modeled on TOCS+ word intelligibility software. 

  • Standard protocols are used to record a child’s productions of the 80 stimulus items and play these back to listeners for judging. 

  • The software recording and playback platform provides a time-efficient procedure for obtaining high quality digital recordings (48 kHz sampling rate and 16-bit quantization) of a child’s productions. 


SIP-CCLP Ver. 4.0
samples phonetic contrasts known to be problematic for speakers with cleft palate (Hodge & Gotzke, 2007).  These include manner preference errors, place preference errors, glottal errors, sibilant errors, voicing errors, and cluster errors. For each of these error types, minimal word pairs that vary systematically in their consonants and that were judged to be familiar to children as young as three years of age were selected as SIP-CCLP items.

Administration:

Deep breathSIP-CCLP software generates a unique order of items for each assessment.  For each item, the software presents a picture and a spoken model for the child to imitate.  The user controls the software to record the child’s production and to save this as a .wav file in the child’s folder. 

 

Judging:
line

SIP-CCLP software is used to play the child’s recorded items to a listener for judging and to record the listener’s responses.
SIP-CCLP has two judging options: Open-set (listener types in the word(s) that he/she hears) and Closed-set (listener selects a word from a multiple-choice array that matches the word that he/she hears) tasks.

  • The open-set task provides intelligibility scores (percent items identified correctly).

  • The closed-set responses can be analysed to profile error patterns that are contributing to the child’s intelligibility deficits at the word level. 

Interpretation:

  • Deep breathTo date, recordings have been collected and analysed from 15 children with cleft palate and 15 age similar children without cleft palate (Gotzke, Hodge, & Daniels, 2006).  Preliminary results based on an earlier version of the SIP-CCLP were reported in Hodge and Gotzke (2007).

  • Measures of speech intelligibility like SIP-CCLP provide valuable summary information about the communicative impact of a child’s speech disorder and the functional benefit of various interventions on a child’s speech ability   These measures also complement information available through existing perceptual and instrumental measures of articulation, resonance and voice characteristics.
