Asked a Canadian, native English speaker, he can't tell the difference between the /p/ in speak and /b/ in beak. I tend to believe the text books that say there are differences is misleading ESL learners.

• s后面的p k t等清辅音(voiceless)一律自动变成b g d等浊辅音(voiced) - HunHunSheng (20 bytes) 2006-2-14, 18:35:35
  • 好像是因为speak中的p不送气，所以我们觉得象b,中文中pb差别在送气否 - AQuestion (96 bytes) 2006-2-14, 19:01:32
    • This is very confusing - Erxin (49 bytes) 2006-2-14, 19:07:39
      • p in speak送气短促象bee中的b,但声带不震动(voiceless)又象pee中的p - AQuestion (117 bytes) 2006-2-14, 20:06:43
  • 不是自动变成浊音，而是因为有了s，影响后面清辅音爆破， - xysReader (82 bytes) 2006-2-14, 18:51:12
    • Do 语音专家s do quantitative analysis, e.g. by MATLAB, or by ears - Erxin (4 bytes) 2006-2-14, 19:04:55
