Patent ID: 7379872

Claim:
A method for processing text for synthesized speech, the method comprising: providing a voice profile including personal prosodic voice characteristic information obtained from an individual, a public key, and an algorithm; encrypting the voice profile to form an encrypted voice profile; providing a text message to be transmitted; generating a message digest of the text message using the algorithm that is included in the voice profile; encrypting the message digest using a private key associated with the public key that is included in the voice profile to form an encrypted digest; outputting the text message, the encrypted voice profile, and the encrypted digest by a first data processing system; receiving the text message, the encrypted voice profile and the encrypted digest by a second data processing system that provides speech synthesis; decrypting the encrypted voice profile by the second data processing system to form a voice profile at the second data processing system, wherein the voice profile at the second data processing system includes (i) the personal prosodic voice characteristic information for the individual, (ii) the public key, and (iii) the algorithm; decrypting, by the second data processing system, the encrypted digest using the public key that is included in the voice profile at the second data processing system to form a decrypted digest; generating, by the second data processing system, a message digest of the text message using the algorithm that is included in the voice profile at the second data processing system; and responsive to a determination that the text message is authentic, by comparing the decrypted digest with the message digest to determine if they match one another and therefore the text message is authentic, generating synthesized speech for the text message using the personal prosodic voice characteristic information for the individual that is included in voice profile at the second data processing system.
