AssemblyAI Review: Is This Speech AI Platform the Right Choice in 2026?
Blog post from Gladia
AssemblyAI has established itself as a prominent platform in the speech-to-text and audio intelligence space, catering to over 5,000 customers with millions of API calls processed daily. Known for its accurate transcription and advanced audio intelligence features, the platform offers a unique framework for applying Large Language Models (LLMs) to speech, making it suitable for developers and enterprises requiring comprehensive voice AI capabilities. While AssemblyAI excels in providing deep audio analysis and enterprise-grade compliance, it has limitations in real-time multilingual streaming and modular pricing complexity. In contrast, Gladia, a newer entrant in the market, focuses on multilingual transcription and audio intelligence, offering over 100 languages for real-time and pre-recorded audio with an all-inclusive pricing model. Founded by Jean-Louis Queguiner and Jonathan Soto, Gladia aims to remain a pure-play speech AI provider, avoiding competition with clients' conversational AI products. The choice between AssemblyAI and Gladia depends on specific needs, such as advanced audio analysis and LLM integration versus broad multilingual support and pricing transparency.
