pydominoの使用例

+
+

pythonライブラリの場合

+
import numpy as np
+import librosa
+import pydomino
+
+alignmer: pydomino.Aligner = pydomino.Aligner("onnx_model/model.onnx")
+wav_source: np.ndarray = librosa.load("example/dowaNgo.wav", sr=16_000, mono=True, dtype=np.float32)[0]
+phonemes: list[str] = ["pau"] + ["d", "o", "w", "a", "N", "g", "o"] + ["pau"]
+alignment_result: list[tuple[float, float, str]] = alignmer.align(wav_source, " ".join(phonemes), 3)
+print(f"{alignment_result}")
+
+
+

とすると、以下のアラインメント結果が得られます

+
[
+    (0.0, 0.07999999821186066, 'pau'),
+    (0.07999999821186066, 0.12999999523162842, 'd'),
+    (0.12999999523162842, 0.20000000298023224, 'o'),
+    (0.20000000298023224, 0.25999999046325684, 'w'),
+    (0.25999999046325684, 0.3400000035762787, 'a'),
+    (0.3400000035762787, 0.44999998807907104, 'N'),
+    (0.44999998807907104, 0.47999998927116394, 'g'),
+    (0.47999998927116394, 0.6800000071525574, 'o'),
+    (0.6800000071525574, 0.7300000190734863, 'pau')
+]
+
+
+

ここで、第3引数の最小割り当てフレーム数を5に変えてみると、とすると、以下のアラインメント結果が得られます

+
alignment_result: list[tuple[float, float, str]] = alignmer.align(wav_source, " ".join(phonemes), 3)
+print(f"{alignment_result}")
+
+
+
[
+    (0.0, 0.07999999821186066, 'pau'),
+    (0.07999999821186066, 0.12999999523162842, 'd'),
+    (0.12999999523162842, 0.20000000298023224, 'o'),
+    (0.20000000298023224, 0.25999999046325684, 'w'),
+    (0.25999999046325684, 0.3400000035762787, 'a'),
+    (0.3400000035762787, 0.4399999976158142, 'N'),
+    (0.4399999976158142, 0.49000000953674316, 'g'),
+    (0.49000000953674316, 0.6800000071525574, 'o'),
+    (0.6800000071525574, 0.7300000190734863, 'pau')
+]
+
+
+

音素 "g" に割り当てられた秒数が 0.03秒から0.05秒に伸びます。これが、最小割り当てフレーム数の保証によるものです。

+
+
+

コマンドラインツールの場合

+

git clone と pip install ./ を使った場合、./build ディレクトリ以下にコマンドラインツールがビルドされます。

+

これによってアラインメントの実行も可能です

+

たとえば

+
$ build/{temporary-directory}/pydomino/domino --input_path example/dowaNgo.wav --input_phoneme "pau d o w a N g o pau" --output_path result.lab -N 5
+
+
+

とすると、以下のアラインメント結果が labファイル（result.lab）に出力されます

+
$ cat result.wav
+
+
+
0.00        0.08    pau
+0.08        0.13    d

日本語音素アラインメントツール pydomino

+
+

pydominoとは

+

pydomino は日本語音声に対して音素ラベルをアラインメントするためのツールです。

+
+
+

使い方

+

pydomino はPythonライブラリとコマンドラインツールの2通りで利用できます。

+
+
+

インストール方法

+
+

Linux / Mac

+

コマンドラインツールがいらない場合はこちらでも直接ライブラリだけインストールできます

+
pip install git+{this-repository-url}
+
+
+
+
+

Windows

+

Anaconda Prompt (miniconda3) 環境において MSVC の vcvars64.bat を利用してインストールします

+

例えば、以下のコマンドでインストールできます

+
# on `Anaconda Prompt (miniconda3)`
+"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"
+git clone --recursive {this-repository-url}
+pip install ./
+
+
+

例示したパスに vcvars64.bat がないなら、例えば以下のような場所にあるかもしれません。

+
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvars64.bat" or
+"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat".
