A method that enhances voice through synthetic speech reinforcement in a speech reinforcement system including one or more microphones (102, 104, 116, 118; 302; 402; 404, 406) for capturing signals from a vehicle occupant and one or more audio transducers for transmitting a reinforcement signal to an intended listener in a vehicle, the method comprising: capturing one or more microphone signals using the one or more microphones (102, 104, 116, 118; 302; 402; 404, 406); estimating a plurality of echo paths from each of the one or more microphone signals, each echo path being between one of the one or more audio transducers and one of the one or more microphones, such that there are J ∗ M echo paths, where J is the number of transducers and M is the number of microphones; processing the captured microphone signals in response to the estimated plurality of echo paths by subtracting the echo contributions of each of the plurality of echo paths from the captured microphone signals, so as to generate feedback and echo cancelled microphone signals; synthesizing a speech reinforcement signal in response to speech detected in the one or more feedback and echo cancelled microphone signals so as to generate a synthesized speech reinforcement signal, wherein synthesizing the speech reinforcement signal includes inferring the speech reinforcement signal from context of the captured one or more microphone signals that are concealed by noise or other signals; and concatenating portions of the synthesized speech reinforcement signal with the captured microphone signals to render the reinforcement signal for transmitting by the one or more audio transducers; wherein the act of concatenating portions of the synthesized reinforcement signal is executed by a dynamic bandpass filter having a passband configured to pass the synthesized speech reinforcement signal to a mixer, by a dynamic bandstop filter having a stopband configured to pass the captured microphone signals to the mixer and by the mixer configured to combine the output of the dynamic bandpass filter and the output of the dynamic bandstop filter to render the reinforcement signal; and wherein the passband of the dynamic bandpass filter and the stopband of the dynamic bandstop filter are automatically controlled in response to detected noise levels and/or detected speech intelligibly measures in the vehicle. capturing one or more microphone signals using the one or more microphones (102, 104, 116, 118; 302; 402; 404, 406); estimating a plurality of echo paths from each of the one or more microphone signals, each echo path being between one of the one or more audio transducers and one of the one or more microphones, such that there are J ∗ M echo paths, where J is the number of transducers and M is the number of microphones; processing the captured microphone signals in response to the estimated plurality of echo paths by subtracting the echo contributions of each of the plurality of echo paths from the captured microphone signals, so as to generate feedback and echo cancelled microphone signals; synthesizing a speech reinforcement signal in response to speech detected in the one or more feedback and echo cancelled microphone signals so as to generate a synthesized speech reinforcement signal, wherein synthesizing the speech reinforcement signal includes inferring the speech reinforcement signal from context of the captured one or more microphone signals that are concealed by noise or other signals; and concatenating portions of the synthesized speech reinforcement signal with the captured microphone signals to render the reinforcement signal for transmitting by the one or more audio transducers; wherein the act of concatenating portions of the synthesized reinforcement signal is executed by a dynamic bandpass filter having a passband configured to pass the synthesized speech reinforcement signal to a mixer, by a dynamic bandstop filter having a stopband configured to pass the captured microphone signals to the mixer and by the mixer configured to combine the output of the dynamic bandpass filter and the output of the dynamic bandstop filter to render the reinforcement signal; and wherein the passband of the dynamic bandpass filter and the stopband of the dynamic bandstop filter are automatically controlled in response to detected noise levels and/or detected speech intelligibly measures in the vehicle.
