A Short Note On Dual Tone Multi Frequency - 1015 Words

What is DTMF? DTMF (dual tone multi frequency) is the signal to the phone company that you generate when you press any key on a telephone’s keypad. The sound is interpreted on the receiving end and can be used to remotely control or interact with devices such as computers, an IVR system or answering machines. How does DTMF work? Picture your phone, specifically the keypad. Each key has its own sound, and each sound is actually two tones played simultaneously. One tone is a low-frequency tone; the other is a high-frequency tone. There are four low-frequency tones which correspond to each row of keys, and three high-frequency tones which correspond to each column. Advantages of DTMF in Call Centers In the contact center industry, DTMF†¦show more content†¦Disadvantages of DTMF in Call Centers 1. Incorrect Keys. Customers often complaint that they accidentally pressed the wrong key while on a call. Callers usually go into panic mode and resort to pressing â€Å"0† to try and get a hold of a live agent. Depending on the caller’s issue, the live agent may have to reroute the caller to a more appropriate support queue. 2. Quantitative Data. Tasks like obtaining stock quotes or making address changes are difficult with touch tone applications, but easier for speech recognition. When customers are put into situations where they have to offer more than just numeric numbers, they usually are routed to a live agent. What is AI? Artificial intelligence (AI) is defined as being â€Å"the ability of a machine to perform at the level of a human expert.† Advantages of Artificial Intelligence in the Call Center 1. Identify Patterns. AI can identify patterns in hours rather than weeks or months like traditional methods. By using these patterns, customer behavior on the phone can be predicted better. 2. Predict Probabilities. Not only can AI predict the likelihood that a creditor will pay their account or the probability that a lead can be converted into a paying customer, it can also analyze agent or rep performances. For instance, are the agents offering a positive experience, are they using enthusiasm and saying things with the utmost confidence? Or, are they speaking likeShow MoreRelatedDsp Manual12055 Words   |  49 PagesC programming/ Equivalent) and hardware (Using TI / Analog devices / Motorola / Equivalent DSP processors). 1.
