A system and a method for single sign-on voice authentication that provides access to multiple voice recognition and artificial intelligence platforms, to multiple devices and to multiple third party web service systems.

System and method for voice authentication

An audio headset that provides a 'chat' mode to temporarily adjusts audio to preset levels to emphasize ambient sound, and includes a beamformer to provide directional speech isolation. The headset may include active noise cancellation and/or passive noise isolation. When entering chat mode, three or more relative audio levels are individually adjusted to presets, allowing the wearer to hear ambient noise and their own isolated voice, while attenuating other audio sources. This user-configurable combination of levels temporarily adjust the mix of signals that will be output to a wearer via the stereo headphone speakers.

Headset mode selection

A communication system, source and destination ports of the communication system, and methodology is provided for transporting data in one of possibly three different ways. Data is transported across the network at a frame sample rate that can be the same as or different from the sample rate or master clock within the source port or the destination port. If the sample rate of the source port is known, the sample rate of the destination port can be created using a PLL within the destination port and simply employing a phase comparator in the source port. Where economically feasible, sample rate conversion can be used at the source. However, sample rate conversion at the destination is preferred if the source sample rate is forwarded across the network relative to the frame transfer rate of the synchronous network. Again, however, sample rate conversion compares relative phase difference changes similar to the phase difference compared in the digital PLL mode. As a further alternative, sample rates within the source and destination ports can be derived from the network frame rate using fractional dividers in the source and destination ports.

Communication system and method for sending and receiving data at a higher or lower sample rate than a network frame rate using a phase locked loop

A communication system, source and destination ports of the communication system, and methodology is provided for transporting data in one of possibly three different ways. Data is transported across the network at a frame sample rate that can be the same as or different from the sample rate or master clock within the source port or the destination port. If the sample rate of the source port is known, the sample rate of the destination port can be created using a PLL within the destination port and simply employing a phase comparator in the source port. The phase comparator forwards the phase or frequency difference of the network transfer rate and the source sample rate to the destination port, which then generates a local clock equivalent to the source which then compiles audio data being played at the same rate in which it was sampled at the source. Where economically feasible, sample rate conversion can be used at the source. However, sample rate conversion at the destination is preferred if the source sample rate is forwarded across the network relative to the frame transfer rate of the synchronous network. The sample rate converter simply produces a play rate from the transmitted information at the destination. Again, however, sample rate conversion compares relative phase difference changes similar to the phase difference compared in the digital PLL mode. As a further alternative, sample rates within the source and destination ports can be derived from the network frame rate using fractional dividers in the source and destination ports.
