Methods, apparatus, and articles of manufacture to generate voices for artificial speech based on an identifier represented by frequency dependent bits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-based interactive devices have limited voice options, making it difficult for users to distinguish between devices, and current systems require complex configuration and maintenance, failing to provide unique voices for each device.
Innovation Solution
The use of unique device-specific identifiers, such as serial numbers or MAC addresses, to personalize artificial speech output, generating distinct voices for each device through audio synthesizers and mixers, allowing devices to produce audibly different voices even when using the same base voice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a limited number of voices are provided in voice-based interactive devices, then device complexity is reduced, but users cannot distinguish between devices and voice personalization is lost
Solution Approach 1:
The patent applies local quality by modifying specific acoustic parameters (pitch, tone, timbre) of the base voice to create device-specific voice characteristics. Each device receives a customized voice variant based on its unique identifier, allowing voice differentiation without requiring multiple complete voice sets or complex configuration systems.
2Loss of information
If multiple voice options are provided for each device, then voice differentiation is improved, but configuration complexity and maintenance burden increase
Solution Approach 1:
The system implements self-service by automatically generating device-specific voice characteristics using the device's unique identifier. The voice personalization process occurs automatically during device initialization without requiring user configuration or manual setup, eliminating the maintenance burden associated with managing multiple voice options while preserving voice differentiation capability.
3Loss of information
If device-specific voice personalization is implemented, then voice distinction between devices is achieved, but system complexity and maintenance costs increase
Solution Approach 1:
The patent implements parameter changes by modifying acoustic parameters (pitch, tone, timbre) of a single base voice based on the device's unique identifier. This approach achieves voice distinction by adjusting voice parameters rather than implementing entirely separate voice systems, significantly reducing system implementation complexity and maintenance costs while preserving full voice differentiation capability.

AI summary
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.
