C-I-SAID (Code-A-Text Integrated System for the Analysis of Interviews and Dialogues) is "a very powerful system for studying documents which integrates qualitative and quantitative methods. The source documents can be text or questionnaires, audio or video."  

C-I-SAID offers a set of unique features which allow the depth of analysis normally associated with a programme dedicated to qualitative analysis, within an analytic framework which is quantitative in orientation. Thus open-ended coding, using comments and textual annotations, is accompanied by rating scales that can be categorical or numerical in format. There are also sections within the programme, such as the lexicon (largely devoted to thematic content analysis) and the acoustic manager (devoted to the measurement of the volume, pitch and speed of speech), that generate statistics. The main outputs from C-I-SAID are reports, tables and charts which can be accompanied by a range of statistics; these can be used to describe the data in tandem with qualitative methods.
