Voice and Speech Analysis in Search of States and Traits

It is the aim of this chapter to introduce the analysis of vocal behaviour and more general paralinguistics in speech and language. By ‘voice’ we refer to the acoustic properties of a speakers’ voice—this will be dealt with in Section 9.2. By ‘speech’ we refer more generally to spoken language in the sense of added linguistics—dealt with in Section 9.3. Obviously, the introduced methods of linguistic analysis can also be applied to written text, albeit with slightly different pre-processing. Also, models trained on written text may differ insofar as spoken language is often grammatically different and possesses more fragments of words, etc.
