GET /v1/models

Lists the models known to this service, including entries that are not downloaded or loaded. Filter supported_endpoints for the API you want, read default_for for defaults, and check execution_location before sending content. Alignment models list /v1/audio/alignments: EdgeSpeak/Lattice-2 is the default and covers every language in the catalog, mixed-language text and und, while EdgeSpeak/Lattice-1 covers Chinese, English and German only and must be requested explicitly.
