Microsoft Gets Patent for Patently Offensive Audio Content
According to the patent abstract, the reason for the invention is that it is common for radio and and television broadcasts of live events to be delayed a few seconds before the audio data is transmitted to enable real-time (censors) content reviewers to evaluate whether the content contains objectionable language. Broadcast television and radio are heeding the demand by the public to essentially "clean up" the airways for the general public and children in particular. The degree of censorship depends on the targeted audience and the nature of the event. Specifically, certain words which are commonly referred to as profanity, obscenities and sexually explicit words are targeted by censors to be unacceptable for public broadcasting.
An input audio data stream comprising speech is processed by an automatic censoring filter in either real time mode or batch mode, producing censored speech that has been altered so the undesired words or phrases are either unintelligible or inaudible. The substituted speech is not bleeped out, but modified in the speakers own voice.
What a wonderful way to hitch onto uncensored Satellite Radio? Hmm, same broadcast, censored with commercials to the existing radios without subscriptions?
