The development and use of original management models prosody to impart the desired color the sound of voices. Change the pitch and tone while maintaining the intelligibility and naturalness of sound. The universal broadband processing (VoIP) and narrowband (telephone) communications channels. Resistance to digitally encoded lossy.
We implemented the Speech improvement technologies in a number of modules in our solutions.
The technology of speech deep transformation that adjusts operator’s voice for better comprehension by the remote user. We have analyzed the over 20 years' scientific research on this subject, and we performed our own additional research in order to determine what kind of voice people consider convincing, confident and serious. These psychological criteria of the voice affect the success of business communication. Our research and the research of other groups suggest that a person with the medium voice pitch frequency is considered a more credible interlocutor. Deep voice modification with preservation of complete naturalness - no "robotic" voice.
The technology of changing voice quality that allows adding appropriate accents to operator's speech. This technology will be helpful for tired users with "fading" voice, unable to naturally add emotions to his/her speech. Such a modification to the speech changes the voice timbre; it is a thin and delicate change, as naturalness and recognition of the voice are not affected. This technology has "cumulative" action, the effect of using it increases with the duration of the dialog, and allows adding appropriate accents to the speech of the user that are unavailable or hard to express to some reason.
Using this innovation, the customer will hear operator's voice better, and will understand his/her speech.
Now the customer won't have to repeat his questions many times and to strain his/her ears so much. Low sounds of the speech will become louder, while the volume of loud sounds will stay the same.
Our technology helps users to hear in a noisy environment, without increasing the volume. Unlike a simple denoiser, which removes the noise from the telephone line, this technology allows the user to hear through the ambient noises. The technology protects users' hearing, as it amplifies selectively only those components of the signal that are masked by the noise, which makes it possible to hear well with the volume only slightly increased.
The technology filters the sound coming to the customer, and removes some harsh sounds that appear when:
