Systematic comparison of 15 surveyed systems mapped onto the five taxonomy dimensions in Table 1 (Section 4.5). The comparison finds "no existing system covers all five dimensions simultaneously" and that lexical stress and content faithfulness are the least-addressed dimensions.

"no existing system covers all five dimensions simultaneously: the most recent system, PresentCoach (Chen et al., 2025), covers four (pronunciation, prosody, pacing, and content) but still omits lexical stress, illustrating that integrated, multi-dimensional coaching remains an open challenge."
