A method comprising receiving audio data 102, generating a transcription 151 comprising a sequence of terms 152, such as “Buy some tomatoes and bananas. Change tomatoes to potatoes”, parallel processing the audio data and the transcription using a multimodal large language model (LLM) 150 to identify one or more revision terms 152R, for example “Change”, specifying a revision action to perform on at least one other term in the sequence, in this instance “tomatoes”, and modifying the transcription 151M accordingly – “Buy some potatoes and bananas”. Identifying the revision term(s) may be based on a corresponding user intent 154 determined for each respective term in the sequence, for example, the user 10 does not intend the final transcription to include “tomatoes”. For each term in the sequence, parallel processing may comprise correlating its speech characteristics 156 such as pitch, tone or prosody information determined from the audio data with its corresponding linguistic context 158 determined from the transcription. Transcription correction may be based on a revision token inserted into the sequence, the token indicating an N number of terms for replacement and their corresponding replacement terms. User context data 104 may be obtained to tailor the LLM to a particular user. [Figure 1A]

This invention belongs to the field of audio processing technology and provides an intelligent accompaniment singing method and system. The method can collect the user's vocal pitch and voiceprint information, then divide the song selected based on the song selection command into vocal data and accompaniment data. The pitch of the accompaniment data is adjusted by comparing the vocal data with the user's vocal pitch, and the audio is played based on the adjusted accompaniment data. The user's singing data is continuously acquired and monitored, and when the user's singing data meets preset conditions, accompaniment vocals generated using the voiceprint information and vocal data are added to the audio. This proposed method can tailor the song's pitch to the user's individual needs, adjusting the accompaniment pitch to a suitable range for the user, ensuring easier singing. It can also selectively add accompaniment vocals based on the user's singing performance, thereby guiding the user to adjust their singing style, improve their singing level, and enhance their singing experience.

The present invention, LYRA (Learning Your Resonance Alignment), is a resonance-based artificial intelligence (AI) system that interfaces with electric guitar hardware to enable adaptive, emotionally intelligent musical performance. LYRA captures real-time input from guitar components, including pickups, sustainers, and toggle interfaces, and analyzes this data through a resonance mapping engine and alignment detection layer to identify a user-specific vibrational and emotional profile. An expression response interface interprets gestures, string vibration, and control interactions, allowing the system to dynamically adjust audio output-including tonal, harmonic, sustain, and effect parameters-based on the musician's alignment. LYRA continuously updates its memory of the user's expressive patterns, providing real-time haptic, visual, or auditory feedback. By integrating seamlessly with existing guitar technologies, LYRA transforms instruments into co-creative partners, facilitating a human-Al musical collaboration that evolves with the performer's style and emotional intent.

To enable the production of good musical tones in response to the user's playing input. [Solution] The CPU of the electronic instrument determines the first pitch that is closest to the pitch corresponding to the pressed key from among the chord tones corresponding to the chord information at the time any key is pressed by the user in the currently playing song. If the first pitch is not being played, the CPU causes the sound-producing part to play at the first pitch. If the first pitch is being played, the CPU causes the sound-producing part to play at the second pitch, which is in the same direction as the first pitch included in the chord tones, relative to the direction of the pitch corresponding to the current key press relative to the pitch corresponding to the previous key press.
