  • Patent number: 8355484
    Abstract: A technique for masking latency in an automatic dialog system is provided. A communication is received from a user at the automatic dialog system. The communication is processed in the automatic dialog system to provide a response. At least one transitional message is provided to the user from the automatic dialog system while processing the communication. A response is provided to the user from the automatic dialog system in accordance with the received communication from the user.

  • Patent number: 8311804
    Abstract: A driving directions system loads into memory a limited subset of prerecorded, spoken utterances of geographic names from a mass media storage. The subset of spoken utterances may be limited, for example, to the geographic names within a predetermined radius (e.g., a few miles) of the driver's present location. The present location of the driver may be manually entered into the driving directions system by the driver, or automatically determined using a global positioning system (“GPS”) receiver. As the vehicle moves from its present location, the driving directions system loads into memory new names from the mass media storage and overwrites, if necessary, those which are now geographically out of range. Based on the current location of the driving, the driving directions system can audibly output geographic names from the run-time memory.

  • Patent number: 8145491
    Abstract: When pitch of a speech segment is being modified from a current pitch to a requested pitch, and the difference between these is relatively large, a pitch modification algorithm is used to modify the pitch of the speech segment. When the difference between current and requested pitches is relatively small, the pitch of the speech segment is not modified. After one or the other speech modification techniques are used, then the resultant modified speech segment is overlapped and added to previously modified speech segments. A modification ratio is determined in order to quantify the difference between the current and requested pitches for a speech segment. The modification ratio is a ratio between the requested and current pitches. Low and high ratio thresholds are used to determine when pitch is being modified to a predetermined high degree, and whether pitch of the speech segment will or will not be modified.

  • Patent number: 7747440
    Abstract: A technique for producing speech output in a text-to-speech system is provided. A message is created for communication to a user in a natural language generator of the text-to-speech system. The message is annotated in the natural language generator with a synthetic speech output style. The message is conveyed to the user through a speech synthesis system in communication with the natural language generator, wherein the message is conveyed in accordance with the synthetic speech output style.

  • Patent number: 7490042
    Abstract: A technique for producing speech output in an automatic dialog system in accordance with a detected context is provided. Communication is received from a user at the automatic dialog system. A context of the communication from the user is detected in a context detector of the automatic dialog system. A message is created in a natural language generator of the automatic dialog system in communication with the context detector. The message is conveyed to the user through a speech synthesis system of the automatic dialog system, in communication with the natural language generator and the context detector. Responsive to a detected level of ambient noise, the context detector provides at least one command in a markup language to cause the natural language generator to create the message using maximally intelligible words and to cause the speech synthesis system to convey the message with increased volume and decreased speed.
