In addition to utterance tiers, it is possible to enrich the annotation of the speech material with any number of other annotation tiers.One must also know the acoustic method and the phonetic factors that may affect the result.įor instance, the Pitch analysis, related to speech melody and intonation, may be misinterpreted unless one knows the limitations of the analysis and defines the analysis parameters in an optimal way. NB: In order to be able to correctly interpret the acoustic measurements, the audio signal must be of sufficiently good quality with reasonably little background noise and no overlapping speech. For instance, it is possible to supplement a CA transcript with a detailed acoustic-phonetic analysis of a particular event within a conversation. Once a transcript has been created with Praat, it may encourage the researcher to apply different acoustic methods for measuring and illustrating conversational speech.It is easy to quickly go back and listen to any desired portion of the original recording that has been annotated with Praat.As the basic transcript has been created using Praat and as the start times of the original utterances can be inserted in the exported transcript, it is easy to find the desired portion in the audio file later. By using the Praat script described below, the researcher may readily use both the audio material and the human-readable transcript in parallel.
