《FreeSWITCH: VoIP实战》：FreeSWITCH 中语音识别

　　至少有关键字 "doesn't exist"

This is not in service. Please check the number and dial again, yeah. How, the bloodhound I should call me a call. If you could take a look at all. The number you have dialed is not in service. Please check the number and dial again.

　　事实证明老四的英文说的不错，英文部分识别的一字不差。

　　结论

　　看来中英混合识别的难度还是比较大的。但我想，不管PSTN的语音再怎么变态，毕竟它是有限的，我们只要采集所有的语音样本，做到100%识别应该是不难的。
