CP Program Information

How does CP work?

To enter an orthographic language sample for analysis you can use either the freeware text editor included with CP or your own word processor. Any word processor can be used as long as it can generate a text file as output. When you type the transcript you must follow a set of simple rules for capitalization, punctuation, speaker identification, etc. If you are familiar with the conventions for the SALT or CLAN programs, you can also type the transcript in either of those formats and then import the file into CP.

Once the transcript is saved as a file, it can be checked for common entry errors. Then, after any errors are repaired, the transcript is automatically "tagged" for its grammatical constituents. Finally, the tagged file is saved as a CORPUS file.

A CORPUS file can be submitted to any one or any combination of CP analysis modules. The language sample needs to be transcribed only once. The time-saving features of CP are especially significant when you need to perform several types of analyses on a single transcript (e.g., a child who exhibits difficulties across the domains of vocabulary, syntax, and phonology). The CP modules work with you to generate codes that result in the final analyses. For example, the LARSP module automatically parses each utterance in a transcript and shows the result to you on the screen. You review the program's analysis and edit the codes where necessary. When you're finished, CP tabulates all the codes and produces the final profile report.

To enter a phonological sample that has been transcribed phonetically the procedure depends on the type of sample. If the sample is from a standard word list such as an articulation test, where the target words are known in advance, you store the words and the phonetic target forms in a file and then retrieve that file as needed. If the sample is spontaneous speech, then you proceed in two steps: first, you create a CORPUS file and enter the orthographic form of the words or utterances you have also transcribed phonetically; then, you run the CORPUS file through a special module of PROPH that retrieves the target forms from a phonetic dictionary. Once the target forms are identified, you enter from the keyboard the form that was actually produced by the child. The keyboard is "mapped" to allow you to enter phonetic characters (e.g., typing S to enter the fricative esh). When you have entered all the forms, CP automatically compares the target and transcription form for each word and generates a PROPH profile report.

The analysis profiles produced by CP are output in the form of text files. These files can be viewed or printed from within CP or they can be imported into other applications. Using a word processor, for example, you can combine several analyses into a single file or merge an analysis file into a clinical report or research paper.
