Do you have a feeling that our tempo of speech accelerates all the time? The media, it seems, have already exceeded all limits in human speech delivery and perception. It's not that they talk too fast; they just don't give us a chance to digest what we hear. In TV news and weather programs the ratio of an uninterrupted speech interval to a pause is 14 to 1, as compared with the ratio of around 3 to 1 in normal conversational speech.
What are the sources?
We studied authentic TV speech. The videotaped corpus was collected in Boston (NBC), New York (NBC Nightly News with Tom Brokaw), Philadelphia (Good Day, Philadelphia!) and Dallas (Texas News Channel 5) in the years 1997 - 2001. We looked at nine samples all in all, spoken by nine newscasters, 5 men and 4 women. Each sample is approximately one minute in duration, or around 200 words long.
When processed and tabulated, the acoustic data, in particular speech-to-pause ratios, were correlated with the geographical origin, type of program and gender of the speakers.
Southern drawl? - No, sir. Quite standard.
Geographically, the North - Midland - South affiliation of newsreaders can be correlated with their rate of speech. Averaged over the regional groups, the ratio of the time spent in talking, as set against the time spent in silence, suggests that the most salient common feature is dominance of talking: 11.4:1, 16.6:1, 15.3:1 (see Table 1).
How are we coping?
Information programs are intended to contain the most important, "top" news. Highlighting the major items is achieved through accent location and pitch change as the acoustic cues which help us pick them out. The average number of accents within the uninterrupted chunks of speech is 6 in newscasting versus 2-3 in other styles, reading and spontaneous talk.
Thus we can re-state the basic findings: newsreader delivery is based on squeezing a lot of information, up to 6 accented items on the average within a 2-3 second time interval which is followed by a short or an extra-short pause. Given the time constraints and the running text to speed them up the newscasters still give us a chance to pick out the main information points by accenting them, without slowing down a bit. We have to rely on visual input and our background knowledge to make sense of the rest of a news item. Or perhaps are the additional details considered to be a restatement of the main point and we are not supposed even to make an effort to grasp them?
