| `splitPunct` | `string`  |                              | (Only for `getAllAudioUrls` and `getAllAudioBase64`) Set the punctuation to split the long text to short text. (e.g. "，、。") |

## Examples

### 1. `getAudioUrl(text, [option])`

```js
import * as googleTTS from 'google-tts-api'; // ES6 or TypeScript
const googleTTS = require('google-tts-api'); // CommonJS

// get audio URL
const url = googleTTS.getAudioUrl('Hello World', {
  lang: 'en',
  slow: false,
  host: 'https://translate.google.com',
});
console.log(url); // https://translate.google.com/translate_tts?...
```

### 2. `getAudioBase64(text, [option])`

```js
import * as googleTTS from 'google-tts-api'; // ES6 or TypeScript
const googleTTS = require('google-tts-api'); // CommonJS

// get base64 text
googleTTS
  .getAudioBase64('Hello World', {
    lang: 'en',
    slow: false,
    host: 'https://translate.google.com',
    timeout: 10000,
  })
  .then(console.log) // base64 text
  .catch(console.error);
```

### 3. `getAllAudioUrls(text, [option])` (For text longer than 200 characters)

```js
import * as googleTTS from 'google-tts-api'; // ES6 or TypeScript
const googleTTS = require('google-tts-api'); // CommonJS

const results = googleTTS.getAllAudioUrls('LONG_TEXT_...', {
  lang: 'en',
  slow: false,
  host: 'https://translate.google.com',
  splitPunct: ',.?',
});
console.log(results);
// [
//   { shortText: '...', url: '...' },
//   { shortText: '...', url: '...' },
//   ...
// ];
```

### 4. `getAllAudioBase64(text, [option])` (For text longer than 200 characters)

```js
import * as googleTTS from 'google-tts-api'; // ES6 or TypeScript
const googleTTS = require('google-tts-api'); // CommonJS

googleTTS
  .getAllAudioBase64('LONG_TEXT_...', {
    lang: 'en',
    slow: false,
    host: 'https://translate.google.com',
    timeout: 10000,
    splitPunct: ',.?',
  })
  .then(console.log)
  // [
