Spontaneous Voice Gender Imitation Abilities in Adult Speakers

چکیده
BACKGROUND The frequency components of the human voice play a major role in signalling the gender of the speaker. A voice imitation study was conducted to investigate individuals' ability to make behavioural adjustments to fundamental frequency (F0), and formants (Fi) in order to manipulate their expression of voice gender. METHODOLOGY/PRINCIPAL FINDINGS Thirty-two native British-English adult speakers were asked to read out loud different types of text (words, sentence, passage) using their normal voice and then while sounding as 'masculine' and 'feminine' as possible. Overall, the results show that both men and women raised their F0 and Fi when feminising their voice, and lowered their F0 and Fi when masculinising their voice. CONCLUSIONS/SIGNIFICANCE These observations suggest that adult speakers are capable of spontaneous glottal and vocal tract length adjustments to express masculinity and femininity in their voice. These results point to a "gender code", where speakers make a conventionalized use of the existing sex dimorphism to vary the expression of their gender and gender-related attributes.

متن کاملVoice-based Age and Gender Recognition using Training Generative Sparse Model
Abstract: Gender recognition and age detection are important problems in telephone speech processing to investigate the identity of an individual using voice characteristics. In this paper a new gender and age recognition system is introduced based on generative incoherent models learned using sparse non-negative matrix factorization and atom correction post-processing method. Similar to genera...

Objectives: Lexical access is the process by which the basic conceptual, syntactical and morpho-phonological information of words are activated. Most studies of lexical access have focused on picture naming. There is hardly any previous research on other parameters of lexical access such as verbal fluency and analysis of connected speech in Persian normal participants. This study investigates t...
متن کاملSpeaker Recognition Robustness to Voice Conversion
Security systems relying on voice identification can be threatened by human voice imitation or synthetic voices. As voice conversion can be seen as a sort of voice imitation, this paper analyses the performance of an automatic speaker identification system by using converted voices in order to know how vulnerable such systems are to this kind of disguise. The experiments are conducted by using ...
متن کاملInvestigation of golden speakers for second language learners from imitation preference perspective by voice modification
This paper investigates what voice features (e.g., speech rate and pitch-formants) make a teacher’s voice preferable for second language learners to imitate, when they practice sentence pronunciation using Computer-Assisted Pronunciation Training (CAPT) systems. The CAPT system employed in our investigation uses a single teacher’s voice as the source to automatically resynthesize several sample...
