The effect of accent on the acoustic cues to stop voicing in Radio News speech
نویسندگان
چکیده
Data from three acoustic cues to stop voicing is analyzed for the effect of phrasal accent in a corpus of read radio news speech from a single speaker of American English. The results show that VOT, Closure Duration and F0 are significant cues to voicing for stops in this corpus, though the acoustic patterns vary by place of articulation. There is a significant effect of phrasal accent on each cue, with increased values for both voiced and voiceless stops, described here as a pattern of syntagmatic strengthening. Patterns of paradigmatic strengthening, with enhanced voicing contrast under accent, are observed only in sporadic cases. The results indicate that accent effects in radio news speech are similar to those reported for “laboratory speech” from prior phonetics studies.

Prosodic effects on acoustic cues to stop voicing and place of articulation: Evidence from Radio News speech
This study examines the effects of prosody on the acoustic cues of stop consonants, based on speech from the Boston University Radio News corpus. An investigation of VOT, f0, closure duration, burst amplitude and spectral characteristics provide evidence for a primary effect of accent (a level of phrasal prominence) on these measures as cues to stop voicing and/or place of articulation. There a...
متن کاملThe Effect of Accent on Acoustic Cues to Stop Voicing and Place of Articulation in Radio News Speech
In previous research evidence for the effects of stress and accent on phonetic variation is based on laboratory speech. In the present paper, we report on a study of the effects of accent on the acoustic cues for stop voicing and place of articulation in the speech of four announcers from the Boston University Radio News corpus. The results show that there are significant effects of accent on V...

Speech production and speech perception studies were conducted to compare (de)voicing in the Romance languages European Portuguese (EP) and Italian. For the speech production part, velar stops in two positions and four vowel contexts were recorded. The voicing status for 10 consecutive landmarks during stop closure was computed. Results showed that during the complete stop closure voicing was a...
