A Text-to-Speech API is a speech synthesizer
that can convert normal language text into speech.
A set of 10 sentences were synthesized and 12 test subjects (Table No.4) having no prior knowledge of speech synthesis system were asked to evaluate the quality of speech synthesizer
. The people who participated in this perceptual test were working persons and graduate students.
His approaches involved approximating vocal-tract characteristics using an all-pole digital-filter model, transmitting its filtering coefficients, and reproducing the original voice with a speech synthesizer
. These methods enabled the speech signal data rate to be reduced to 1/10 to 1/20 of that for the pulse-code modulation (PCM) method, which transmits speech data using the direct digitization of speech waveforms.
A speech synthesizer
audibly makes the owner aware of the dog's intentions, which also appears on the screen of the wireless hand-held unit.
Studies that have compared discourse presented in natural and synthetic speech with individuals without disabilities have revealed that the accuracy of comprehension is dependent on the quality of the speech synthesizer
This posed a major problem because Jayne not only relies on the computer for e-mail and Web access but also to talk through a speech synthesizer
Some features are big-ticket items, such as a multi-lingual software speech synthesizer
and translator that convert conversations into typed words, and gates that open automatically.
RealSpeak Pin-Yin also leverages RealSpeak technology and the speech synthesizer
available in the current generation of SSFT6040 chips.
DECtalk technology is the smallest fully featured speech synthesizer
in the world, offers personalized voices, and has extensive user controls to ensure optimum performance in real-world applications.
The speech synthesizer
used by NaturallySpeaking sounds less robotic than IBM's ViaVoice, but the rhythm of the speech is often rather odd.
Also, data from sentence verification tasks reflect slower reaction times to judge th e truth of sentences spoken by a speech synthesizer
than for natural speech sentences (Pisoni, Manous, & Dedina, 1987).
