AIに歌を聞かせた。そして彼は笑顔😃になった。(COTOHA-感情分析API)

Last updated at Posted at 2020-02-27

概要

歌を聞かせた。
彼はその歌を聴き、
Positiveな感情になると笑い😃、
Negativeな感情になると怒り😠、
Neutralな感情になると。。。😐

(COTOHAの感情分析APIを使って、歌の歌詞からどのような感情をくみ取るのかを試した。COTOHA API for Developersに登録してすぐに、感情分析APIを試せるようWEBアプリも作った。)

結果

とりあえず歴代CDシングル売り上げ枚数ランキングを聞かせた。
「1位から順に！カウントアップ！👆」

WEBアプリ化

COTOHA API for Developersに登録した人限定ではあるが、同じ遊びが出来るようにした。（簡単に登録可）
以下URLで遊ぶには、登録後に取得できる、Client IDとClient secretが必要。
https://cotoha-demo.now.sh/

2020-02-26_17h32_04.png
Client IDとClient secretは、画面リフレッシュのたびに入力しなおすのは面倒。なので、ブラウザのlocalstrageにて情報を保持している。

技術

アプリ化に伴い、以下の技術を使用。

  • Nuxt.js【JavaScript framework】
  • ant-design-vue【Css framework】
  • Now【Deploy】
  • Express【API】
server.js
server.js
const express = require('express')
const request = require('request')
const app = express()

// server
const port = process.env.PORT || 5000
app.listen(port, err => {
    if (err) throw err
    console.log(`> Ready On Server http://localhost:${port}`)
})

// API
app.get('/getToken', function(req, res, next) {
    (() => {
        return new Promise(r => {
            if (req.query.ClientID && req.query.Clientsecret && req.query.AccessTokenPublishURL){
                const AccessTokenPublishURL = req.query.AccessTokenPublishURL
                const ClientID = req.query.ClientID
                const Clientsecret = req.query.Clientsecret
                const headers = {
                    'Content-Type': 'application/json'
                }
                const data = {
                    'grantType': 'client_credentials',
                    'clientId': ClientID,
                    'clientSecret': Clientsecret
                }
                const options = {
                    url: AccessTokenPublishURL,
                    method: 'POST',
                    headers: headers,
                    json: data
                }
                request(options, (error, response, body) => {
                    return r(body)
                })
            }else{
                r('Parameter is incorrect')
            }
        })
    })().then(data => {
        res.send(data)
    }).catch(error => {
        res.send(error)
      })
})

app.get('/cotohaApiSimilarity', function(req, res, next) {
    (() => {
        return new Promise(r => {
            if (req.query.sentence && req.query.token){
                const sentence = req.query.sentence
                const token = req.query.token
                const headers = {
                    'Content-Type': 'application/json;charset=UTF-8',
                    'Authorization': `Bearer ${token}`
                }
                const data = {
                    'sentence': sentence,
                }
                const options = {
                    url: 'https://api.ce-cotoha.com/api/dev/nlp/v1/sentiment',
                    method: 'POST',
                    headers: headers,
                    json: data
                }
                request(options, (error, response, body) => {
                    return r(body)
                })
            }else{
                r('Parameter is incorrect')
            }
        })
    })().then(data => {
        res.send(data)
    }).catch(error => {
        res.send(error)
      })
})

あとがき

他のAPIと組み合わせれば、話す内容によって表情を変えるbotが簡単に出来そう。

あと要約(β)API・キーワード抽出API・言い淀み除去(β)・音声認識誤り検知(β)・音声認識API　ここら辺のを使って、音声データから議事録を作るWEBアプリ（WEBサービス）作りたい。。。時間が欲しい。。。

おまけ

Q.　さて、これは誰が歌っているのさくらの結果でしょうか？？？↓
