Speech basis fashions have lately achieved exceptional capabilities throughout a variety of duties. Nevertheless, their analysis stays disjointed throughout duties and mannequin sorts. Totally different fashions excel at distinct points of speech processing and thus require totally different analysis protocols. This paper proposes a unified taxonomy that addresses the query: Which analysis is suitable for which mannequin? The taxonomy defines three orthogonal axes: the analysis facet being measured, the mannequin capabilities required to try the duty, and the duty or protocol necessities wanted to carry out it. We classify a broad set of current evaluations and benchmarks alongside these axes, spanning areas resembling illustration studying, speech era, and interactive dialogue. By mapping every analysis to the capabilities a mannequin exposes (e.g., speech era, real-time processing) and to its methodological calls for (e.g., fine-tuning information, human judgment), the taxonomy offers a principled framework for aligning fashions with appropriate analysis strategies. It additionally reveals systematic gaps, resembling restricted protection of prosody, interplay, or reasoning, that spotlight priorities for future benchmark design. Total, this work affords a conceptual basis and sensible information for choosing, deciphering, and lengthening evaluations of speech fashions.
