Sound Control Device Syllable Pronunciation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound control devices for musical instruments and electronic musical instruments do not adequately align syllable pronunciation with a performer's intent, particularly in controlling sound generation during note-off operations.
Innovation Solution
A sound control device that includes an obtainer, a determiner, an identifier, and an instructor. The device obtains performance information, identifies note-ons and note-offs, identifies syllables from lyrics data corresponding to note-ons, and instructs the pronunciation of syllables to start at note-ons and end at note-offs, with specific control over phonemes including end consonants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If syllable pronunciation is controlled only by note-on operations, then the sound generation starts at the correct timing, but the syllable pronunciation does not align with the performer's intent regarding end timing
Solution Approach 1:
The syllable pronunciation control is segmented into two independent phases: note-on triggers syllable start, and note-off triggers phoneme end. This segmentation allows precise control of pronunciation timing without requiring a completely complex control system, as each phase is handled by a simple trigger event.
Solution Approach 2:
The system performs preliminary identification of syllables from lyrics data before sound generation occurs. By pre-identifying which syllable corresponds to each note-on event, the system prepares the pronunciation sequence in advance, ensuring accurate alignment without adding runtime complexity.
2Measurement precision
If end consonants are pronounced at note-on timing, then the syllable starts pronunciation early, but the end consonant timing does not match the performer's intent
Solution Approach 1:
The system dynamically adjusts phoneme pronunciation timing based on the note-off event. Instead of using a fixed timing rule for all phonemes, the end consonants are specifically timed to start at note-off, allowing the pronunciation to adapt to the performer's actual ending intent while maintaining simple operation.
3Reliability
If syllable pronunciation is controlled without considering note-off, then the control system remains simple, but the pronunciation accuracy regarding performer intent deteriorates
Solution Approach 1:
The system uses note-off events as feedback to adjust phoneme pronunciation timing. By monitoring when the performer releases the note, the system receives feedback about the intended ending point and adjusts the end consonant pronunciation accordingly, improving reliability without significantly increasing system complexity.

AI summary
A sound control device includes an obtainer, a determiner, an identifier, and an instructor. The obtainer obtains performance information. The determiner identifies a note-on or a note-off based on the performance information. The identifier identifies, from lyrics data, a syllable corresponding to a timing at which the determiner identified the note-on. The lyrics data includes a chronological arrangement of a plurality of syllables to be pronounced. The instructor instructs the syllable identified by the identifier to start being pronounced at a timing corresponding to the note-on, and causes at least one phoneme among phonemes constituting the identified syllable to start being pronounced at a timing corresponding to the note-off.
