Powered by their Solaria ASR model, Gladia delivers transcription with less than 300 milliseconds latency, making it ideal for voice AI agents, contact centers, and real-time communication applications. Gladia combines advanced speech recognition with audio intelligence features like sentiment analysis, named entity recognition, and automatic language detection, providing a comprehensive solution for voice-driven applications.Why choose Gladia for voice AI transcription?
Gladia offers several features that make it a powerful choice for real-time speech recognition:- Ultra-Low Latency: With sub-300ms latency, Gladia enables natural, responsive conversations without noticeable delays, essential for voice AI agents and real-time applications.
- Extensive Language Support: Supports over 100 languages interchangeably, making it suitable for global deployments and multilingual customer interactions.
- Code-Switching Support: Handles seamless language switching within conversations, accurately transcribing when speakers alternate between languages like English and Hindi (Hinglish) or other language combinations.
- Custom Vocabulary: Allows boosting recognition of specific words, phrases, brand names, or industry-specific terminology to improve accuracy for specialized use cases.
- Native Mulaw Support: Directly supports mulaw audio encoding used by Twilio, eliminating the need for audio conversion and reducing latency in telephony applications.
- Audio Enhancement: Built-in audio preprocessing improves transcription accuracy in challenging conditions with background noise or poor audio quality.
- Configurable Endpointing: Adjustable silence detection thresholds allow fine-tuning for different conversation styles and turn-taking patterns.
- Sentiment Analysis: Real-time sentiment detection helps understand caller emotions and enables dynamic agent responses.
How does Bolna integrate with Gladia?
Bolna AI integrates Gladia’s STT technology to enable real-time, high-accuracy speech transcription for its AI-powered voice agents. Here’s how Bolna leverages Gladia:- Real-Time Voice Processing: Bolna uses Gladia’s streaming WebSocket API to convert spoken language into text in real time. The two-step connection process (session creation followed by WebSocket connection) ensures reliable, authenticated streaming with optimal performance.
- Multilingual Voice Agent Support: With support for over 100 languages, Bolna voice agents can handle conversations in virtually any language. When code-switching is enabled, agents can accurately transcribe conversations where speakers switch between languages.
- Telephony Provider Optimization: Bolna automatically configures audio encoding based on the telephony provider. For Twilio, it uses native mulaw at 8kHz (wav/ulaw); for Exotel and Plivo, it uses linear16 at 8kHz; and for web-based calls, it uses linear16 at 16kHz for optimal quality.
- Audio Enhancement for Telephony: Bolna enables Gladia’s audio enhancer for telephony providers (Twilio, Exotel, Plivo) to improve transcription accuracy in real-world call conditions with background noise and varying audio quality.
- Custom Vocabulary Integration: Bolna supports passing custom vocabulary keywords to Gladia, allowing voice agents to accurately recognize company names, product names, and industry-specific terminology.
- Intelligent Turn Detection: Bolna leverages Gladia’s configurable endpointing to accurately detect when users have finished speaking. The endpointing threshold can be adjusted to balance responsiveness with accuracy for different conversation styles.
- Code-Switching for Multilingual Markets: For markets like India where code-switching is common, Bolna configures Gladia to recognize both the primary language and English, enabling accurate transcription of mixed-language conversations.
