How to transcribe audio from a mobile app (iOS/Swift, Android/Kotlin, React Native)

A tutorial details the secure method for integrating AssemblyAI's transcription service into mobile applications without a dedicated mobile SDK, emphasizing the importance of not embedding API keys within client-side code due to security concerns. It suggests a design involving lightweight clients for iOS, Android, and React Native that record audio and send it to a server-side backend, which securely stores the API key and communicates with AssemblyAI's REST API. This approach not only protects the API key but also provides advantages like request logging, rate limiting, and the flexibility to update models without redistributing the app. The tutorial provides implementation guidelines for the backend using Node or Python and instructions for developing mobile clients in Swift, Kotlin, and React Native, ensuring the API key never leaves the server. Additionally, it discusses setting up a pipeline for file transcription and offers insights into implementing real-time streaming transcription using temporary tokens.
