“Can you speak louder? I can’t hear you.” How many times have we uttered those words? Oftentimes, out of sheer desperation, we just disconnect from the call, as the poor audio quality mixed with background noise makes speech unintelligible. This experience may not be around much longer, however, if high definition (HD) Voice goes mainstream.
Thus, TEO, the Lithuanian fixed-line telephony operator, is planning to offer new business Internet telephony service subscribers the chance to try out HD voice service in October.
TEO is one of ten fixed-line operators in the European Union to offer HD voice calls.
So, what makes HD voice clearer than traditional, standard-definition audio? Usually ordinary audio calls are transmitted on a frequency of 300 Hz to 3.4 kHz. HD voice, on the other hand, transmits between 50 Hz to 7 kHz. Normal human speech includes sounds above 3.4 kHz, so any tones not falling within the audio spectrum are lost during ordinary audio calls. However, the wider frequency of HD voice captures speech and the natural inflections without any loss in quality.
The result is there for all to see – clear conversations, crisp audio clarity, natural sounding speech, limited background noise, no fading of calls and no more swallowed phrases. Hence, HD voice can go a long way toward improving customer service for businesses and telephony service providers, including in the development of IVR systems.
As the HD voice playback function is supported by most next-generation Internet telephony telephone sets, even automatic answering machines will be improved. HD voice will also provide a more accurate environment for voice recognition and speech detection.
"As more and more businesses are transitioning to VoIP services, High Definition (HD) quality will gradually become a mandatory component of business calls, or even a standard,” said Nerijus Ivanauskas, chief marketing officer of TEO.
TEO predicts that this service will become extremely popular among call centers and other companies that pay special attention to customer service over the phone. Companies that wish to serve customers faster and better would be well served to jump onto the HD voice bandwagon.
