Cheap mcu does not have enough MIPS to perform speech recognition.You must need DSP to do real time speech recognition.Microchip dspic is a good choice which is not too expensive and it has some libraries for you.

本人刚开始做蓝牙，现在用的是CSR8645。对Microchip dspic不熟悉，请问Microchip dspic也是基于蓝牙的应用吗？可以用Microchip dspic开发 单耳式蓝牙耳机吗？谢谢！

No, Microchip dspic is mcu with dsp capability.It is general purpose mcu, not specific for Bluetooth application.If you need speech recognition on Bluetooth headset, the best approach is still work on BC5-MM but this will need more software work on SDK.

Hope this is helpful to you.

用CSR8645开发的蓝牙耳机，可以实现通过蓝牙耳机 语音拨打、接听、挂断
及发送短信的功能，前提是另一MCU控制

谢谢大侠指点！

BC5-MM我知道，是flash版本的，和CSR8670一样，只是后者的版本高而已。
对8670我司也评估过，最后决定用CSR8645平台。
