## DAF Pro Description
DAF Pro帮助口吃者和帕金森病患者放慢语速，说话更流畅。戴上耳机开口说话，几分之一秒后就能听到自己的声音。

工作原理
延迟听觉反馈（DAF）是临床认可的言语治疗技术。以短暂延迟听到自己的声音，会自然放慢语速，让说话更顺畅、更清晰。研究表明，DAF对约三分之一的口吃者有帮助，也用于帮助帕金森病患者控制语速。

适用人群
* 口吃者
* 帕金森病患者
* 构音障碍患者
* 迅吃者
* 言语治疗师：用于治疗课程和居家练习

功能
* 可调节延迟时间和音调
* 处理延时极低，设置的短延迟不会被拉长
* 可在后台和屏幕关闭时持续运行
* 录制并回放自己说的话
* 支持有线和蓝牙耳机。蓝牙会带来额外延迟，因耳机而异，使用短延迟时建议选择有线耳机。

开始使用
戴上耳机，将延迟设置为约50–100毫秒，按“开始”并说话。然后逐步调整，直到说话感觉更慢、更平稳。

由英国言语治疗师开发。一次买断：无订阅、无广告、无需注册账号。

## DAF Pro Reviews in China

### ****- "不知道为什么听录音每次短句的最后一个声音都一会大一会小的"
不知道为什么听录音每次短句的声音都一下大一下小的
-- diang海, 2026-01-27

### *---- "别下载，骗子软件"
也不知道这个评论能不能被看到，比较十三个评论就显示了三个，功能完全不能用，就是个摆设，苹果那边也不给退费，买了就只能被气死。千万别买，拿口吃圈钱的简直不得耗si
-- 是执子啦, 2025-10-21

### ****- "版本更新以后，开降噪直接没声音"
版本更新以后，开降噪直接没声音，望改进
-- 月小石, 2025-03-05

### ****- "反馈"
使用感受有一个问题，带蓝牙耳机时延迟时间较长，做不到同步播放声音，而直接听手机话筒没问题，希望可以改进这一点
-- 努力开放音, 2024-11-03

### ***** "功能很适合我需求"
对我这样需要矫正发音的人来说 帮助很大，能及时且听别人声音一样听到自己声音 ，这样才能很好的比较发音（有比较对象）
