Continuous audio analytics by HMM and Viterbi decoding ... We address the problem of audio analytics with respect to efficient modeling of audio classes and continuous decoding of audio stream to automatically segment and label the audio stream as required in audio indexing. We propose the use of left-to-right HMMs and ergodic HMMs to ...

https://ieeexplore.ieee.org/document/4518061
Short-time Viterbi for online HMM decoding: Evaluation on a real-time phone recognition task Abstract: In this paper we present the implementation of an online HMM decoding process. The algorithm derives an online version of the Viterbi algorithm on successive variable length windows, iteratively storing portions of the optimal state path.
ECTURE Viterbi Decoding of Convolutional Codes
http://web.mit.edu/6.02/www/f2010/handouts/lectures/L9.pdf
Soft decision decoding (also sometimes known as “soft input Viterbi decoding”) builds on this observation. It does not digitize the incoming samples prior to decoding. Rather, it uses a continuous function of the analog sample as the input to the decoder. For example, if the expected parity bit is 0 and the received voltage is 0.3 V, ...
