The assimilation model describes personality as a community of voices, where separate voices are traces of distinct or partly unintegrated experiences. Internal voices reflect on each other and engage in dialogical interactions within the person. This study's hypothesis is that dialogues between internal voices can be literally heard in clients' speech in therapy. We present a trial study of two assimilation methods for detecting voices, applied to 16 clients from the Second Sheffield Psychotherapy Project (cognitive behavior therapy for severe or moderate depression, one best session per client). Three clinically sophisticated raters independently identified clients' voices in therapy transcripts, listed their descriptions and examples, and rated voices on affect / personality attributes using Wiggins' Interpersonal Adjective Scale (IAS). Next, raters they consensualized their voice selections and independently rated voices on the IAS again. Then raters they listened to the audiotapes of these passages, to check if the vocal data changed their selections and descriptions. Finally, a different group of independent raters, exposed to short audiotaped segments only, classified these selections into voices, and rated them on the IAS. We discuss results of these 4 rounds, and their implications for detecting internal multiplicity and understanding dialogical self through the theory of voices.
