description: Speak (Speakeasy Labs, Inc.) is an AI-powered language learning application focused on spoken fluency rather
  than grammar drills or vocabulary memorization. Its proprietary "Speak Method" has learners study real phrases, practice
  them across contexts, and then apply them in back-and-forth conversation with an AI tutor that gives real-time pronunciation
  and fluency feedback. Speak teaches Spanish, French, Korean, Japanese, Italian, German, and Chinese, plus English for non-English
  speakers, and offers B2B language training for organizations across Korea, Japan, Spain, Taiwan, and France. The company
  is backed by Accel and the OpenAI Startup Fund and partners with OpenAI. Speak runs a production application backend at
  api.usespeak.com (an OAuth2/OIDC issuer) but does not publish a public developer API, OpenAPI specification, or SDKs; the
  surfaces below were discovered from the company's public well-known and llms.txt endpoints.
