From 4a2684be341f26e273249e2b58a17b92dfc68d84 Mon Sep 17 00:00:00 2001 From: Enno Hermann Date: Fri, 24 Nov 2023 12:24:42 +0100 Subject: [PATCH] fix(bin.synthesize): more informative error for wrong --language argument (#3294) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In multilingual models, the target language is specified via the `--language_idx` argument. However, the `tts` CLI also accepts a `--language` argument for use with Coqui Studio, so it is easy to choose the wrong one, resulting in the following confusing error at synthesis time: ``` AssertionError: ❗ Language None is not supported. Supported languages are ['en', 'es', 'fr', 'de', 'it', 'pt', 'pl', 'tr', 'ru', 'nl', 'cs', 'ar', 'zh-cn', 'hu', 'ko', 'ja'] ``` This commit adds a better error message when `--language` is passed for a non-studio model.
