【IBM】人工知能ワトソンspeach to text実況中継

更新日:

IBMの人工知能ワトソンは無料でかなりの部分が一般開放されています。

そこで、今回、ワトソン君の【speach to text】(音声認識)の機能を実況中継動画で紹介してみます。

IBMの株価はさほど好調ではありませんが、ワトソン君はいたって優秀です。

【speach to text】にいたっては、人間以上の多言語の文字起こし能力を発揮してくれるので、そのデモ機能を紹介してみます。

IBMワトソン【speach to text】実況中継

まずは動画でワトソンの秀才ぶりをご覧あれ。

speach to text demoで実際にやってみた文字起こしの記録です。

日本語と英語のニュースをどの程度、文字起こしできるのかを見てみます。

まずは、世の中を騒がしたコインチェック騒動の報道から。

ニュースの出元はNHK報道です(金融庁 コインチェックに業務改善命令

多少、間違い入力もありますが、後で人間が直せば、すぐに原稿にできる下書きを用意する能力があることが分かります。

ワトソン君はライターの優秀なアシスタントになってくれるでしょう。

次に英語でのトランプ大統領とキャスターの問答の文字起こしを見てみます。

こちらはCNBCのインタビュー。二人の音声を見事に英語でワトソンは拾っています。

日本人でここまで二人の対話を英語で拾ってくれる文字起こしを雇ったらいくらかかるのでしょうか。

ワトソン君は優秀なマルチリンガルライターなのです。

ワトソンの文字起こしの精度を検証してみる

CNBCの原文とワトソンの文字起こしをポイントを絞って比べてみます。

CNBC記事が黒、ワトソンが青(不一致部分が赤)で前半部分を比べます。

(CNBC記事は編集されているので、不一致部分=誤記とは限りません)

全体的な傾向を見ると、ワトソンのspeaker1と2はトランプとCNBCキャスターの発言に必ずしも一致せず、TPPがtwo-ppになったり、NAFTAがafterになったり、人名のLighthizerで苦戦したりしています。

ただ、それがあるにせよ、全体的には8割以上の精度があるようなので、かなり驚異的な性能です。

日本人がこれだけの文字起こしをするには、相当の訓練を経なければいけないでしょう。

-------------------------

Trump: I like bilateral, because if you have a problem, you terminate.When you're in with many countries — like with TPP, so you have 12 if we were in — you don't have that same, you know you don't have that same option.But somebody asked me the other day, 'Would I do TPP?' Here's my answer — I will give you a big story.

--------------------------

Speaker 1: Girl because if you have a problem you terminate when you're in with many countries like with you PP so you have twelve if we were in you you don't have that same you know you don't have that same option but somebody asked me the other what I do to be be his financial can be a big story.

----------------------------

I would do TPP if we made a much better deal than we had.We had a horrible deal. The deal was a horrible deal.NAFTA's a horrible deal, we're renegotiating it.I may terminate NAFTA, I may not — we'll see what happens.  But NAFTA was a — and I went around and I tell stadiums full of people, I'll terminate or renegotiate.

Kernen: So you might re-enter, or? Are you opening up the door to re-opening TPP, or?

-----------------------------

Speaker 1: I would do two PP if we made a much better deal that we had we had a horrible deal the deal was a horrible deal nafta is a horrible deal were re negotiate again I may terminate after I may not we'll see what happens but nafta was a and I went around and I told.

Speaker 2: Stadiums full of people so you might re enter we are you opening up the door to re opening.(下線部はカレン氏の発言)

-------------------------------

Trump: I'm only saying this. I would do TPP if we were able to make a substantially better deal. The deal was terrible, the way it was structured was terrible. If we did a substantially better deal, I would be open to TPP.

--------------------------------

Speaker 1: I'm only saying this I would do TPP if we were able to make a substantially better deal the deal was terrible the way it was structured was terrible if we did a substantially better deal I would be open to TPP.

-----------------------------------

Kernen: That's interesting. Would you handicap ... ?

Trump: Are you surprised to hear me say that?

Kernen: I am a little bit, yeah, I'm a little taken aback.

Trump: Don't be surprised, no, but we have to make a better deal. The deal was a bad deal, like the Iran deal is a bad deal, these are bad deals.

Kernen: Maybe NAFTA, maybe not NAFTA, can you give me any indication of which way you're leaning because there's a lot of people, a lot of the CEOs that have been on here, they all seem to acknowledge that it's 30 years later and there's a lot of changes that make a lot of sense, but to not abandon the deal. Will you —

Trump: Hey Joe, we have a trade deficit with Mexico. Mexico, $71 billion a year, right?

-----------------------------------------

Speaker 2: That's interesting arm.

Speaker 2: Would you hand you said rice the eyes I'm a little bit yeah we'll take the prize but we have to make about one and a deal is a bad deal Iran deal is a deal maybe even after maybe not now can you give me any.

Speaker 2: Indication which way you're leaning at because there there's a lot to a lot of the the CEO that have been on here they all seemed to to acknowledge that it's thirty years later and there's a lot of changes that make a lot of sense but to not abandon the date we join we have a trade deficit.
Speaker 1: With Mexico Mexico seventy one billion dollars a year right.

(※二人が高速で会話を続けたので、このあたりはワトソンも苦戦しています)

-----------------------------------------

Trump:We have a trade deficit with Canada of a substantial amount of money. I have a number, but they keep arguing it, they keep saying, so I won't say it, I won't tell you it's $17 million, OK? We have a trade deficit with Canada. We have a massive trade deficit with Mexico. We've got to do something. We can't continue to do this.

Kernen: Are you leaning towards staying in or would you really go out completely?

---------------------------------------------

Speaker 1: We have a trade deficit with Canada of a substantial amount of money I have in a number but they keep arguing they keep saying that's I won't say it I will tell you what seventeen million dollars okay we have a trade deficit with with Canada we have a massive trade deficit with Mexico gonna do something we can't.

Speaker 2: Continue violating towards staying and or or would you really.

------------------------------------------------

Trump: I've always said ... during campaign and as you have noticed, and as you have actually said a couple of times which I have always appreciated, I have fulfilled a lot of what I've said and I'm only here a year, you know I think I have four years, and maybe another four years, OK? … Joe,

-------------------------------------------------

Speaker 1: Go I've always said during the campaign and as you noticed as you've actually said a couple of times which I've always appreciated I have fulfilled a lot of what I've said animal here a year you know I.
Speaker 2: Think I have.
Speaker 1: For years and maybe.
Speaker 2: Another four years okay mostly on our you know see what happens so.

-----------------------------------------------------

Trump: we have a $71 billion a year deficit with Mexico. We've got to do something, we can't have that. So, will it be renegotiated? We're trying right now with [U.S. Trade Representative] Bob Lighthizer and the whole group. I think we have a good chance but we'll see what happens.

---------------------------------------------------------

Speaker 1: We have a seventy one billion dollar a year trade deficit.
Speaker 2: With Mexico.
Speaker 1: Consists of we can't have that so will be renegotiated with trying right now with Bob lie as or the whole group.
Speaker 1: I think we have a good chance but we'll see what happens.

---------------------------------------------------------

ワトソンとお友達になるには

ここまで見て、ワトソンの性能に恐れをなした方もいるかもしれません。

そのうち、文字起こしという職種は絶滅。速記という仕事もなくなりそうだからです。

恐るべきマルチリンガル出現ですが、人工知能の台頭そのものは止められないでしょう。

そこで、筆者の提案は「ワトソンとお友達になり、その性能をみんなで活かそう」という結論になります。

昔のイギリスの労働者のように機械の打ちこわし運動をしても先はないからです。

筆者はワトソンをプログラム言語を用いて利用する能力はないので、デモ版の使い方を紹介しておきます。

  • 前掲サイトに飛び、Voice Modelで、用いる言語を選択。
  • Upload audioで (.mp3, .mpeg, .wav, .flac, opus)の音声ファイルをアップロード。

後は自動で文字起こししてくれます。

ただ、動画はキャプチャーソフトを用いて、それをMP3等に変換しなければいけません。

筆者はbandicom(キャプチャー)とAiseesoft(動画⇒音声変換)を使いました。

これでワトソン君とお友達になれます。

IBMの株価とトータルリターンはワトソン君ほど優秀なパフォーマンスではないようですが、今後の急騰を期待したいものです。

(参考:IBMの指標。ブルームバーグHPを2018/1/29閲覧)

  • 株価52週レンジ:139.13 - 182.55
  • 1年トータルリターン:-10.38%
  • 年初来リターン:1.80%
  • 株価収益率(PER) :11.7
  • 12ヶ月1株当り利益 (EPS) :13.35
  • 株価売上高倍率(PSR) :1.84
  • 直近配当利回り(税込):3.84%

株価推移は以下の通りです。

【3ヶ月】

【3年】

【長期】

2018年にIBMはどうなるのでしょうか。
