Current System Repertoires
We are often asked why Real Voice
and not Text To Speech? Here are some examples of
the reasons why…..Voice Perfect - Destinations
Text to Speech - Destinations
What makes Voice Perfect different to other systems?We think just listening will answer that Question…….
Sample Announcement (Hybrid) Voice Perfect (Real Voice)
What Makes a ‘Good Announcement’

Institute of AcousticsMeasuring Intelligibility of SpeechThe Modified Rhyme Test, tests for both initial and final consonant apprehension (Logan et al. 1989, Goldstein 1995). The test consists of 50 sets of 6 one-syllable words which makes a total set of 300 words. The set of 6 words is played one at the time and the listener marks which word he thinks he hears on a multiple choice answer sheet. The first half of the words are used for the evaluation of the initial consonants and the second one for the final ones. The Table opposite summarises the test format (Shiga et al. 1994).

Error RatesLogan et al. (1989) have presented this test for nine synthesizers and natural speech. They also performed an open response version of the test and found out that the intelligibility decreased significantly when the multiple choice answer sheet is excluded. The results are summarized in Figure opposite where the three error rates for each synthesizer are shown for the initial consonants, the final consonants, and the average of these respectively. The test and the results are also summarized in Santen et al. (1997).
Male vs. Female? The Basic requirement of voice messages is clarity and
comprehensibility of the messages. It is generally true that a female voice is more likely to be heard,
because of its pitch in relation to the background noise in the environment (Airport or Noisy Station)
The female voice is more pleasing – therefore used for information The male voice is more authoritative – therefore used for emergency
