The improved ALD model is benchmarked against four leading market providers, demonstrating industry-leading accuracy in detecting spoken languages. This update allows users to build multilingual applications with higher accuracy and more control, providing better insights and experiences for customers. AssemblyAI's API supports 17 languages in the Best Tier and 99 in Nano, simplifying multilingual application development and reducing maintenance time. The ALD model also introduces customizable confidence thresholds, allowing users to set minimum confidence levels for language detection and ensuring only high-certainty transcriptions are processed.
