Abstract: Voice user interfaces can be tested using test scripts generated by traversing a graph using a recursive search technique, such as recursive depth first search. Test data to accompany the test scripts can be generated by treating conditions in states of the interface as business rules, and fully exercising each state during traversal of the graph. Actual testing can be performed in a faster than real time manner by providing simulated input from test scripts, as opposed to requiring actual input from human testers. The interfaces can also be tested using a gatekeeper intermediary which provides for easy transitions between testing and deployment.

Abstract: A method, system, and medium are provided for generating a profile for public safety answering platforms. The profile identifies media formats or media format combinations that are supported by the PSAPs at various cell sector locations maintained by a network provider. A network server selects a cell sector and generates test emergency services calls. The test emergency services calls are transmitted to a PSAP but are optimized to reduce a number of test emergency services calls based on media support included in the profile of the PSAP. The PSAP generates a response that indicates whether the PSAP supports a media format identified in the test emergency services call. The PSAP may rely on capabilities of a secondary PSAP to generate the response. The PSAP transmits the response to the network server for storage in the profile.

Abstract: A method and apparatus for creating spatialized sound, including the operations of determining a spatial point in a spherical coordinate system, and applying an impulse response filter corresponding to the spatial point to a first segment of the audio waveform to yield a spatialized waveform. The spatialized waveform emulates the audio characteristics of a non-spatialized waveform emanating from the chosen spatial point. That is, when the spatialized waveform is played from a pair of speakers, the played sound apparently emanates from the chosen spatial point instead of the speakers. A finite impulse response filter may be employed to spatialize the audio waveform. The finite impulse response filter may be derived from a head-related transfer function modeled in spherical coordinates, rather than a typical Cartesian coordinate system. The spatialized audio waveform ignores speaker cross-talk effects, and requires no specialized decoders, processors, or software logic to recreate the spatialized sound.

Abstract: In many audio playback systems, frequencies below a given cut off frequency are suppressed either due to speaker constraints or safety constraints. For example, some speakers are only capable of generating signals above a certain frequency. Prolonged low frequency sound can cause damage to speakers or other components. An audio driver can be equipped with a phantom bass module which by doubling, tripling and/or quadrupling frequencies below a cutoff frequency can simulate the bass experience. The doubling, tripling and quadrupling methods disclosed provide a low complexity formulation of a frequency doubling, tripling and quadrupling. In addition, the frequency doubling, tripling and quadrupling formulations are easily adapted to multi-rate processing, where computational savings can be very high.
