Methods, apparatus, and articles of manufacture to generate voices for artificial speech based on an identifier represented by frequency dependent bits
First Claim
1. An apparatus comprising:
- an artificial speech generator to;
mix a first artificial speech signal with a voice personalization signal to generate a modified artificial speech signal, the first artificial speech signal representing text, the voice personalization signal corresponding to a subset of sounds associated with the first artificial speech signal, the subset of sounds corresponding to a subset of frequency bands in a frequency-domain representation of the first artificial speech signal;
identify the subset of sounds based on an identifier, the identifier to uniquely identify the apparatus from a plurality of other apparatus, the identifier defined by a string of bits; and
assign individual bits of the string of bits to different ones of the frequency bands, the subset of the frequency bands corresponding to the subset of sounds identified based on values of the individual bits; and
an output device to output an audible signal based on the modified artificial speech signal, the audible signal to be audibly different to a human listener from other audible signals generated by respective ones of the plurality of other apparatus for the same text.

Abstract
Methods, apparatus, and articles of manufacture to generate voices for artificial speech are disclosed. An example apparatus includes a component storing an identifier, the identifier uniquely identifying the apparatus from a plurality of apparatus, an artificial speech generator to generate a first artificial speech signal representing text, the first artificial speech signal generated based on the identifier which is represented by frequency dependent bits by assigning specific bits to specific frequency bands, the first artificial speech signal audibly different from artificial speech signals generated by respective ones of the plurality of apparatus for the text, and an output device to output an audible signal representing the first artificial speech signal.

22. A method comprising:
-
converting text to an initial artificial speech signal; generating a voice personalization signal corresponding to a subset of sounds associated with the initial artificial speech signal, the subset of sounds corresponding to a subset of frequency bands in a frequency-domain representation of the initial artificial speech signal, the subset of the frequency bands selected based on an identifier, the identifier defined by a string of bits, the subset of the frequency bands corresponding to the subset of sounds identified based on values of individual bits of the string of bits assigned to different ones of the frequency bands; combining the initial artificial speech signal with the voice personalization signal to generate a modified artificial speech signal, the identifier to uniquely identify an apparatus from a plurality of apparatus; and outputting an audible signal from the apparatus based on the modified artificial speech signal, the audible signal being audibly different to a human listener from other audible signals output by respective ones of the plurality of apparatus for the text.

23. A non-transitory computer-readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
convert text to an initial artificial speech signal; generate a voice personalization signal corresponding to a subset of sounds corresponding to a subset of frequency bands in a frequency-domain representation of the initial artificial speech signal, the subset of the frequency bands selected from the initial artificial speech signal based on an identifier, the identifier defined by a string of bits, the subset of the frequency bands corresponding to the subset of sounds identified based on values of individual bits of the string of bits assigned to different ones of the frequency bands; combine the initial artificial speech signal with the voice personalization signal to generate a modified artificial speech signal, the identifier to uniquely distinguish the machine from other machines; and output an audible signal based on the modified artificial speech signal, the audible signal to be audibly different to a human listener than another audible signal output by a respective one of the other machines for the text. - View Dependent Claims (24, 25)
