Gladia outperforms AssemblyAI on real-time accuracy, latency, and conversational performance
Gladia outperforms Assembly AI on real-time accuracy, latency, and conversational performance
AssemblyAI wasn't built for real-time conversation. Gladia was. With human-like latency and accuracy, Gladia powers natural, uninterrupted speech, so every interaction feels effortless and in sync.
Dozens of teams have shared their AssemblyAI migration stories with us. Anonymized for privacy, their feedback surfaces consistent, real-world pain points worth considering.
Data privacy concerns
“For European companies, all the data routes through the U.S. with AssemblyAI, and even if they don’t store it, it still raises GDPR issues.”
Poor real-time accuracy
“Accuracy in real-time was never that good.”
Limited multilingual support
“They have limited support in terms of real-time languages.”
Poor language detection
“We tested AssemblyAI and noticed strange transcription artifacts. For example, when transcribing Slovak audio, it frequently mixed in Czech forms. It made the result difficult to read.”
Technical performance issues
“We weren’t happy with Assembly’s latency or endpoint detection. Accuracy was fine for general use, but the real-time detection made it frustrating to work with.”
Privacy shouldn’t be a premium
At Gladia, data privacy is non-negotiable. We never use your audio to retrain our models, and we don’t believe in charging extra for peace of mind.
AssemblyAI model retraining policy means your conversations can be used to improve their AI unless you pay to opt out.
We think that’s wrong. Your data is not a bargaining chip.
