英文启蒙节目的语音用机器学习转成文本，so easy！

平时有时会用中文语音转文本，省下打字的力气，那个准确率真高。

那么英文语音转文本，效果如何？

初体验的感觉是：转换英文启蒙节目的语音，已经胜任。

我用了史提夫趣味英语一段4分钟的节目，语音转换平台是讯飞听见，地址是：https://www.iflyrec.com/entrans/intro.jsp

这个平台的英文语音转文本，正处于测试阶段，一个用户每天可以免费上传2条英文语音测试。只要语音长度不超过1个小时，5分钟就给出完整的文本结果。

史提夫趣味英语一段4分钟的节目，一共转了500多一点英文单词，准确率目测在85%，文字错误主要来自于布偶Maggie的夸张语音。主要缺点是，不能自动加上标点符号，后期自己校正文本，还是花了一些功夫。

这还是国产平台的测试结果。谷歌，微软，都有英文语音转文本的平台，美国人搞出来的，准确率相比会是更高。我准备近期都测试一下，真心觉得这个功能太实用了。

由此说句题外话：翻译这一行，会继续发展，但被大量的机器学习取代，是无可避免的了。

以下是我测试用的视频和调整后的文本。
