opaque structure (will become a class)
| unsigned int SprAcmod::flags |
set of flags (SPR_AM_CALC_... + SPR_AM_CVT_...)
| int SprAcmod::vlen |
number of parameters in the input vector
| int SprAcmod::Nstates |
number of states, only filled in a an HMM is attached to the mvg (also indicates whether the state info is available)
| int SprAcmod::Ngauss |
number of gaussians in the set
| int SprAcmod::TotMixdim |
total length of the mixture arrays
| float SprAcmod::log_sf |
LOG: multiply the log likelihoods/posteriors returned by calc_oprob() with log_sf obtain natural logs; LIN: raise the likelihoods/posteriors returned by calc_oprob() to the power log_sf to obtain linear values
| float SprAcmod::asf |
LOG: <cvt_optob>() returns natural log likelihoods/posteriors multiplied with asf; LIN: <cvt_optob>() returns likelihoods/posteriors raised to the power asf
| float SprAcmod::H |
the entropy (log(perplexity), not log2) of the posterior probs represented by oprob
| float SprAcmod::log_tot_lik |
the unconditional likelihood corresponding to oprob
| float SprAcmod::floor_frac |
floor value for state outputs
| float* SprAcmod::prior |
the state priors
| float* SprAcmod::lprior |
the log of the state priors
| double SprAcmod::Npoints |
total number of points
| SprHmmTProb* SprAcmod::tprob |
transition probs of the HMM
| float* SprAcmod::oprob |
output probabilities of the states
| SprHmmFGauss** SprAcmod::gaussians |
gaussians + state links
| SprHmmUchar* SprAcmod::state_sel |
mark the active states
| SprHmmUchar4* SprAcmod::sel |
gaussians selected by FRoG
| SprHmmUchar4* SprAcmod::orig_sel |
pre-selection of gaussians (lexicon/sentence based during recognition/alignment or state based during training)
| SprHmmRmgInfo* SprAcmod::frog |
fast evaluation of gaussians
| _FuncPtr2_HMMDEF_ SprAcmod::calc_oprob |
the main evaluation function: computes the (log) likelihood or the (log) posterior prob; the actual format of the output of this routine is described by the flags flags (and the scale factor log_sf)
| float*(* SprAcmod::cvt_oprob)(SprAcmod *gset, float *restrict oprob) |
convert to output of calc_oprob(); the default conversion creates scaled log likelihoods (scale factor asf) and computes the unconditional probability of the observation
| _FuncPtr3_HMMDEF_ SprAcmod::modify |
modify the status/configuration
| int(* SprAcmod::check_keys)(const SprAcmod *gset, const SprKeySet *keys) |
check if the observation is compliant with the acoustic model
| _FuncPtr4_HMMDEF_ SprAcmod::call_back |
the acoustic model requires a call-back from the search (feedback loop)
| SprAcmod*(* SprAcmod::free)(SprAcmod *gset) |
free all data
