Native Mode: Song (Singing Synthesis) - VOICEVOX for Laravel

Singing in native mode

Native-mode singing synthesis calls VOICEVOX CORE directly through PHP FFI. Score and Note structures are shared with client mode.

Prerequisites

Complete Installation and Configuration
Set up VOICEVOX Core for PHP
Set VOICEVOX_CORE_PATH in .env

VOICEVOX_CORE_PATH=/path/to/voicevox_core/

For singing models, confirm s0.vvm is included in core.vvms in config/voicevox.php.

Create `Score` and `Note`

use Revolution\Voicevox\Song\Note;
use Revolution\Voicevox\Song\Score;

$score = Score::make([
    Note::make(length: 15),
    Note::make(length: Note::len(ticks: 480, bpm: 120), lyric: 'ド', key: 60),
    Note::make(length: Note::len(480, 120), lyric: 'レ', key: 62),
    Note::make(length: Note::len(960, 120), lyric: 'ミ', key: 64),
    Note::make(length: 2),
]);

Basic usage

use Revolution\Voicevox\Song\Note;
use Revolution\Voicevox\Song\Score;
use function Revolution\Voicevox\song;

$score = Score::make([
    Note::make(length: 15),
    Note::make(length: Note::len(480, 120), lyric: 'ド', key: 60),
    Note::make(length: Note::len(480, 120), lyric: 'レ', key: 62),
    Note::make(length: Note::len(960, 120), lyric: 'ミ', key: 64),
    Note::make(length: 2),
]);

$response = song($score, teacher: 6000)
    ->generate(id: 3001);

$response->storeAs('native', 'song.wav');

The same Score can be reused in both client and native modes.

Re-sync F0 and volume with `tap()`

tap() is useful in native song mode as well. Tune SongAudioQuery, then continue to generate().

use Revolution\Voicevox\Song\SongAudioQuery;
use function Revolution\Voicevox\song;

$response = song($score, teacher: 6000)
    ->tap(function (SongAudioQuery $song) {
        $song->sync();
    })
    ->generate(id: 3001);

If updating separately, always run in this order:

->tap(function (SongAudioQuery $song) {
    $song->updateF0();
    $song->updateVolume();
})
