AssemblyAI has released a Ruby SDK, making it easier to use their Speech AI models with Ruby programming language. The SDK allows users to transcribe audio files, analyze audio using intelligence models, and apply LLMs (Large Language Models) to audio data using LeMUR. Three examples are provided: transcribing an audio file from a URL or local file, using LeMUR for LLM applications on voice data, and utilizing audio intelligence models for sentiment analysis. The Ruby SDK can be found in the GitHub repository with installation instructions and documentation available.
