YouTube, Deepspeech, with Google Colaboratory [testing_0002]

Last updated at Posted at 2021-02-15

English

deepspeech-0.9.3-models

This version is not backwards compatible with earlier versions.

この記事は、YouTube 動画から音声をとって、deepspeech という英語の音声から音声認識してテキストにするプログラム（スピーチレコグニション とか ASR とか呼ばれているもの）を Google Colabratory で使うもののテストのノートです。おもしろそうなので。

deepspeech 0.6.1に対応していた記事を、deepspeech 0.9.3に合わせて書き直しました。ファイル構成とコマンドがより以前のバージョンとは異なっているので、今後にも同様な違いが現れると思いますのでバージョンを確認してください。

Google Colabratoryについて

よくある質問
基本
Colaboratory とは何ですか？
Colaboratory（略称: Colab）は、Google Research が提供するサービスです。Colab では、誰でもブラウザ上で Python を記述、実行できるため、機械学習、データ分析、教育に特に適しています。具体的には、GPU などのコンピューティング リソースに無料でアクセスしながら特別な設定なしにご利用いただけるホスト型の Jupyter Notebook サービスです。

本当に無料で利用できるのですか？
はい。Colab は無料でご利用いただけます。

話がうますぎるように思えます。なにか制限事項があるのではありませんか？
https://research.google.com/colaboratory/faq.html

YouTube 動画からの音声の取得の部分は youtube-dl が担当し、deepspeech は英語話者の音声に対して自動スピーチ認識をして対応するテキスト推量して表示します。（ 以下のプログラムについては deepspeech-0.9.3-models / TensorFlow1 が使われています。）

これはつまり、「すぐできる」ものですが、 deepspeech-0.9.3-models のデータサイズが そこそこ 容量があることには注意してください。
ただし、設定を残さない場合は、 Google Colabratory ランタイム終了とともにデータも消えます。

むずかしそうな字が並んでいるように感じます。でも、端的に書きますが、以下の python コードを googlecolab のセルに貼りつけて実行していくだけです2。
googlecolab では　Control キー + Enter キーでセルのコードを実行できます。
いちばん心理的に障壁が高いのは、 google のアカウントをつくることですが、それ以上の難しさはここには無いです。しかしまた、実行する必要もないです。知りたい人のためにサンプルとして、しばしここにあるだけです。よく見直すと、 python プログラムというよりターミナルでコマンド並べているという感じです、ここでは。シェルの補助として python ぽいので書いているだけで、ほとんど要らない、省こうと思えば、シェルだけでいいような気がします。googlecolab を使うことにメリットがあるので googlecolab が　IPython だから使用言語が python であるということですね。

googlecolab ではエディターの設定で vim のキーバインディングが可能なので、vim だと速い人は、Shift キー + insert キーでペーストできます。

Speech Recognition with DeepSpeech

このワードで検索してみてください。以下の引用は全てここからのものでした。バージョンの違いもありますから、違いを認識した上で改良を加えるなりしてください。実際に動作するサンプルを見ないと、なかなか手が出ないので、レシピノートを公開してくれていることでプログラムの動作チェックできて、ありがたく思います。

Install DeepSpeech

from os.path import exists
import wave

!pip install -q deepspeech-gpu==0.9.3 youtube-dl

if not exists('deepspeech-0.9.3-models.pbmm'):

pre-trained model ... 学習済みのモデルってことでしょうね。

  • .pbmm ... TensorFlow runtime が参照するモデル

  • .tflite ...　TensorFlow Lite runtime　が参照するモデル。こっちはraspberry pi とかに使われる lite 版用ってことですね。　

ということがここに書いている。
https://deepspeech.readthedocs.io/en/v0.9.3/USING.html#getting-the-pre-trained-model

もうひとつ

  • .scorer　

この記事の中で使うのは、
deepspeech-0.9.3-models.pbmm
deepspeech-0.9.3-models.scorer
の2つです。このモデルが deepspeech プログラムから参照される。

Transcribe Youtube Video

We are going to make speech recognition on the following youtube video

GoogleColaboratory

YouTubeVideo(video_id)

Download the above video, convert to a WAV file and do speech recognition

GoogleColaboratory
#!rm -rf *.wav
!youtube-dl --extract-audio --audio-format wav --output "extract.%(ext)s" {urltext}

youtube-dl --extract-audio --audio-format wav --output "test.%(ext)s" で extract.wav というファイル名で wav フォーマットで動画から抽出します。deepspeech が対応するのはサンプリングレート 16000hz の音声のようです。

このテストケースでも、かならずしも YouTube の音声でなくてもいいので、youtube-dl のインストールが済んでない場合、 ffmpeg がインストールされていないかもしれません。音声のコンバートに別途 ffmpeg が必要な場合はこれでインストールできます。

!apt install ffmpeg
GoogleColaboratory
!ffmpeg -i extract.wav -vn -acodec pcm_s16le -ac 1 -ar 16000 -f wav test.wav

deepspeech ではデフォルトでは 16000hz の wav に対応しているらしいので、 44100 Hz:extract.wav の音声ファイルを PCM signed 16-bit little-endian 16000 Hz:test.wav へコンバートします。

deepspeech の自動スピーチ認識（ ASR ）の結果は、

確認してみてください。まだ速くする方法など、色々わからないので、結構待つことになるので「リダイレクション '>'」（シェルコマンド）てやつで、出力をテキストファイルにしておくといいかもしれません。3

1    you may write me down in history with
2    your bitter twisted lies
3    you may tribe me in the very dirt but
4    still like dust a lie does my sassiness
5    upset you
6    why are you beset with gloom just
7    because I walked as if I have oil wells
8    pumping in my living room just like
9    moons and like Suns with the certainty
10    of tides just like hope springing high
11    still I rise did you want to see me
12    broken bowed head and lowered eyes
13    shoulders falling down like teardrops we
14    can buy my soul who cries does my
15    sassiness upset you don't take it too
16    hard just cuz I laugh as if I have gold
17    mines digging in my own backyard you can
18    shoot me with your words you can cut me
19    with your lies you can kill me with your
20    hatefulness but just like life arise
21    just my sexiness offend you oh does it
22    come as a surprise that I dance as if I
23    have diamonds at the meeting of my
24    thighs
25    out of the huts of history's shame I
26    rise up from a past rooted in pain I
27    rise a black ocean leaping and wide
28    Welling and swelling and bearing in the
29    time leaving behind nights of terror and
30    fear I rise into a daybreak miraculously
31    clear I rise bringing the gifts that my
32    ancestors gave I am the hope and the
33    dream of the slave and so there go
