Latest Patents
One of Claude Cesaro's latest patents is titled "Method and system for transmitting a DTMF signal with compressed voice in a packet switching network." This invention discloses a system and method for transmitting DTMF signals over high-speed digital networks using voice compression algorithms. It ensures the integrity of DTMF signals at the destination node after the compression and decompression of data on a voice connection. A DTMF Detector is placed in parallel with a voice compression unit, filtering out higher frequency components to prevent double DTMF detection. When a candidate DTMF signal is validated, only the essential data for reconstituting the DTMF signal is transferred to the destination node.
Another significant patent is "Voice activity detection method and apparatus using the same." This method detects the presence of voice, single tone, and dual tone signals by comparing a ratio of the maximum value of the received signal during a sampling period to a measure of energy against three different thresholds. This innovative approach allows for accurate detection of voice signals, enhancing communication clarity.
