r'''清掉 actions.py 里重复的 list_voices 和残留的旧 say 前半段。

== 怎么弄出来的 ==

fix_tts_fallback.py 里我写了两处替换，但 `NEW` 那个大块**自己也带了一份
list_voices**：

    t.replace(OLD_VOICES, NEW_VOICES)   # 这是第一份 list_voices
    t.replace(OLD_SAY,    NEW)          # NEW 里又有一份 list_voices

于是 pyflakes 报：

    redefinition of unused 'list_voices' from line 540
    redefinition of unused 'say' from line 575
    local variable 'chosen' is assigned to but never used

第三条是**旧 say 的前半段残留** —— `chosen` / `speed` 算完就不用了，
真正干活的在后面那份里。

== 这一版怎么改 ==

把**后面**那份 list_voices（`NEW` 带进来的）删掉，保留前面 NEW_VOICES 那份；
再把旧的 say 前半段（算 chosen/speed 那几行）删掉 —— 那些在新 say 里
已经算过一遍了。

**先全部定位好再动手**，避免又改一半。
