+## [2.0.0](https://www.github.com/googleapis/nodejs-text-to-speech/compare/v1.4.1...v2.0.0) (2019-11-14)
+
+
+### ⚠ BREAKING CHANGES
+
+* move library to typescript code generation (#285)
+
+Starting with this release, the auto-generated library code was changed from JavaScript to TypeScript, so all the TypeScript types are now exported from the `.d.ts` files.
+
+Please note that if you used `@types/google-cloud__text-to-speech` package to get TypeScript types for this library, you need to stop using it and remove it from your `devDependencies`.
+
+If you see any issues caused by this migration to TypeScript, please feel free to submit an issue!
