Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic musical instruments struggle to control intonation in real-time for rap performances and other musical styles, limiting accessibility and expressiveness for users, especially beginners.
Innovation Solution
A keyboard instrument with a processor-driven system that allows users to digitally synthesize voice data in real-time by using a combination of operation elements and statistical parametric speech synthesis based on deep learning, enabling precise control over intonation patterns for each segment of voice data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If concatenative synthesis is used to automate singing, then pitch can be specified in time with automatic progression, but intonation cannot be controlled in real time
Solution Approach 1:
The patent divides the singing performance into discrete time segments, with each operation element controlling intonation for a specific time segment. This segmentation allows automated progression while enabling independent real-time control of intonation for each segment through operation elements like sliders or knobs.
Solution Approach 2:
The patent introduces dynamic control through operation elements that allow real-time adjustment of intonation parameters during performance. The intonation data changes dynamically based on operation element values, enabling flexible control without breaking the automated flow.
2Adaptability or versatility
If sophisticated intonations are applied in rap and other musical performances, then expressiveness is enhanced, but operation complexity increases
Solution Approach 1:
The patent makes the operation elements universal by allowing them to control multiple aspects of performance including pitch, intonation, and timing. This multi-functionality enables sophisticated intonations without requiring separate controls for each parameter, reducing overall operational complexity.
Solution Approach 2:
The patent enables sophisticated intonations by allowing users to adjust intonation parameters through operation elements. By changing parameters like intonation magnitude and timing through simple operations, complex expressive effects become accessible without increasing device complexity.
3Ease of operation
If real-time digital synthesis of voice data with intonation control is implemented, then accessibility for beginners is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service system where the processor automatically handles complex synthesis and intonation application based on simple operation element inputs. Beginners only need to adjust operation elements while the system autonomously performs the complex digital synthesis and intonation control, making the system accessible despite internal complexity.

AI summary
A keyboard instrument includes at least one processor that determines a first pattern of intonation to be applied to a first time segment of a voice data on the basis of a first user operation on a first operation element, causes a first singing voice for the first time segment to be digitally synthesized from the first segment data in accordance with the determined first pattern of intonation, determines a second pattern of intonation to be applied to the second time segment of the voice data on the basis of a second user operation on a second operation element, and causes a second singing voice for the second time segment to be digitally synthesized from the second segment data in accordance with the determined second pattern of intonation.
