Functional voice disorders are accordingly reinterpreted as emergent consequences of suboptimal operational configurations, reorienting clinical practice from symptom description toward identification of underlying system disorders. A diagnostic model maps symptoms to operational deficiencies, supported by measurable indices including subglottal pressure estimation, cepstral peak prominence (CPP), H1-H2, and SPL/effort ratio. Three illustrative case models-hyperfunctional phonation with restricted high-range projection, hypofunctional instability with breathy phonation, and register discontinuity at passaggio-each trace presenting symptoms to operational causes and specify intervention targets.

I then address assessment challenges in multilingual individuals with aphasia and suggest that, when appropriate, multilingual people could be evaluated and treated in a context that allows them to employ their complete linguistic repertoire rather than in a context in which they have to select one target language and inhibit the other(s). This new assessment practice can then alleviate added cognitive and affective demands associated with language selection and inhibition, and can provide ecologically valid information about the communication abilities of the individual. This new approach is suitable for multilingual people who tend to use their multiple languages with their interlocutors, and may be less relevant for those multilingual people who use their languages in a diglossic manner.
