Return a `Array<Array<String>>`. If one of Han is heteronym word, it would be have multiple pinyin.

## Options¶

#### `<Boolean> options.segment`¶

Enable Chinese word segmentation. Segmentation is helpful for fix heteronym problem, but performance will be more slow, and need more CPU and memory.

Default is `false`.

## Q&A¶

### What's the different Node version and Web version?¶

`pinyin` support Node and Web browser now, the API and usage is complete same.

But the Web version is simple than Node version. Just frequently-used dict, without segmentation, and the dict is compress for web.

Because of Traditional and Segmentation, the convert result will be not complete same. and the test case have some different too.

Feature | Web version | Node version
--- | --- | ---
Dict | Frequently-used Dict, Compress. | Complete Dict, without Compress.
Segmentation | NO | Segmentation options.
Traditional | NO | Full Traditional support.
