Recent evidence has indicated that a word's morphological family and inflectional paradigm members get activated when we produce words. These paradigmatic effects have previously been studied in careful, laboratory context using words in isolation. This previous research has not investigated how the linguistic context affects spontaneous speech production. The current corpus analysis investigates paradigmatic and syntagmatic effects in Estonian spontaneous speech. Following related work on English, we focus on morphemic and non-morphemic word final /-s/ in content words. We report that linguistic context, as measured by conditional probability, has the strongest effect on the acoustic durations, while inflectional properties (internal structure and inflectional paradigm size) also affect word and segment durations. These results indicate that morphology is part of a complex system that interacts with other aspects of the language production system.

Abstract In psycholinguistics there is an agreement that self-monitoring is part of the speech production system, it serves the repair of speech errors and disfluencies occurring during the process of speech production. During simultaneous interpreting, where source language speech perception and target language speech production happen simultaneously, the analysis of self-monitoring is of particular importance. In our study we compare self-monitoring processes in the target language texts, interpreted from English into Hungarian, of professional interpreters and trainee interpreters. We examine the frequency of incidence of error – type disfluencies, the editing phase of self-repairs, the frequency of incidence of disfluencies, and the editing phases of repetitions and restarts. Although our data have revealed considerable individual differences between interpreters, some tendencies can be detected. In general, differences can be detected in self-monitoring between professional and trainee interpreters. When compared to data about self-monitoring processes in spontaneous, monolingual Hungarian speech, we can state that there were far fewer phenomena connected to self-monitoring in the target language output of simultaneous interpreters than in monolingual Hungarian texts.

AbstractWe argue that a comprehensive model of human vocal behaviour must address both voluntary and involuntary aspects of articulate speech and non-verbal vocalizations. Within this, plasticity of vocal output should be acknowledged and explained as part of the mature speech production system.

Speech production substitutes to reconstruct speech functions have been developed and used practically to vocalize speech of those who have lost voice functions, but have problems. We focused on PZT ceramic vibrators as a sound source for an artificial larynx. We first produced the artificial larynx, which uses PZT ceramic vibrator; and then evaluated its performance. The voice of the power spectrum of the artificial larynx user is similar to that of the speaking person's voice. The vocalized sound of the artificial larynx user shows good characteristics at format frequency, which is important for vowel discrimination. The resonant frequency of PZT ceramic vibrator is high, however and it is difficult to generate sound near 125Hz for PZT ceramic vibrators. We studied how to lower the frequency of generated sound by using added mass.
