Explore how to use Vue to implement text-to-speech

Vue Text-to-Speech With the continuous development of artificial intelligence technology, voice technology has gradually entered our lives. For example, smart speakers, smart voice assistants, etc. all require the use of natural language processing and speech synthesis technology. As the Vue framework becomes more and more widely used in front-end development, some developers have also begun to explore text-to-speech application scenarios in Vue.

Let’s introduce how to use Vue to implement text-to-speech.

1. Use the iFlytek speech synthesis API

First, we need to use the iFlytek speech synthesis API. iFlytek is a leading artificial intelligence company in China, providing a number of technical services such as speech synthesis and speech recognition. The speech synthesis API can convert text into speech.

Next, we need to register an account and obtain the AppID, API Key and API Secret according to the official documents provided by iFlytek. After successful acquisition, we can use tools such as Ajax or Axios to obtain the voice data by sending a request to the iFlytek server.

2. Create a Vue component

Next, we need to create a Vue component to convert the text in the input box into speech. The component needs to have a text input box, a voice play button and an audio control. The code is as follows:

<template>
  <div>
    <input type="text" v-model="content" placeholder="请输入要转换的文本">
    <button @click="textToSpeech">语音合成</button>
    <audio ref="audio"></audio>
  </div>
</template>

<script>
  import axios from 'axios'

  export default {
    data() {
      return {
        content: ''
      }
    },

    methods: {
      textToSpeech() {
        if (!this.content) {
          alert('请输入要转换的文本')
          return
        }

        axios({
          method: 'get',
          url: 'http://api.xfyun.cn/v1/service/v1/tts',
          headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
          },
          params: {
            text: encodeURI(this.content),
            voice_name: 'xiaoyan',
            speed: '50',
            volume: '50',
            pitch: '50',
            appid: '您的AppID',
            apikey: '您的API Key',
            timestamp: new Date().getTime(),
            signa: ''
          }
        }).then(response => {
          let blob = new Blob([response.data], { type: 'audio/mp3' })
          this.$refs.audio.src = URL.createObjectURL(blob)
          this.$refs.audio.play()
        }).catch(error => {
          console.log(error)
        })
      }
    }
  }
</script>

The above code converts the text in the input box into speech and plays the speech through the audio control. Among them, you need to replace AppID and API Key with your own. At the same time, in order to prevent cross-domain problems, it is necessary to set the Content-Type in the request header and add timestamp and signature information to params.

3. Component introduction

Finally, we need to introduce the component into the main page for users to use. The code is as follows:

<template>
  <div>
    <TextToSpeech></TextToSpeech>
  </div>
</template>

<script>
  import TextToSpeech from './components/TextToSpeech.vue'

  export default {
    components: {
      TextToSpeech
    }
  }
</script>

The above is the process of using Vue to implement text-to-speech. It is worth noting that since the iFlytek speech synthesis API charges a fee, you need to pay attention to the number of API calls during use. In addition, you also need to pay attention to user privacy issues and comply with relevant privacy regulations.
