Features
Higgs Realtime
Higgs Realtime is Boson AI’s real-time speech-to-speech model for conversational voice applications.
It allows an AI agent to receive spoken input, reason about the conversation and respond with generated speech without relying entirely on a traditional speech-to-text, text model and text-to-speech pipeline.
The model is designed for applications such as customer support lines, sales conversations and voice-enabled product assistants.
Real-Time Speech-to-Speech
Boson AI supports direct conversational speech experiences where users can talk naturally with an AI system and receive spoken responses.
The technology is designed to maintain low latency so conversations feel more immediate.
Interruption Handling
Higgs Realtime is designed to handle interruptions during conversation.
When a person interrupts the AI, the system can adjust its response rather than simply completing a previously generated statement. This can make voice interactions feel closer to natural human conversations.
100+ Languages
Higgs Realtime supports more than 100 languages, making it suitable for international voice applications.
Higgs TTS 3 also supports expressive speech generation across more than 100 languages.
Higgs TTS 3
Higgs TTS 3 is Boson AI’s text-to-speech model designed specifically for conversational voice AI.
Instead of simply reading text aloud, the system is designed to produce speech with more natural timing, expression and conversational behavior.
Emotion and Style Control
Developers can control how generated speech sounds through inline instructions.
Supported controls include emotion, speaking style, speed, pitch, pauses, prosody and sound effects. This gives developers more control over how an AI voice communicates.
Voice Cloning
Boson AI provides zero-shot voice cloning capabilities.
A short voice reference can be used to reproduce characteristics of a speaker’s voice, helping organizations create consistent voices for appropriate authorized applications.
Higgs STT 3
Higgs STT 3 is Boson AI’s speech-to-text and automatic speech recognition model.
It supports 94 languages and combines speech recognition with language detection, sentiment analysis and semantic understanding.
Sentiment Detection
Boson AI’s audio technology can detect emotional signals within speech.
Businesses can potentially use this information for smarter routing, conversation analytics and context-aware voice agent behavior.
Audio Understanding
Higgs Audio is designed to understand more than the literal words being spoken.
Its audio models can consider elements such as tone, emotion, intent and surrounding audio context, allowing developers to build richer voice applications.
Tool Calling
Higgs Realtime supports tool calling.
This allows a voice agent to interact with external systems and business information while conducting a conversation. For example, a customer support agent could potentially retrieve information about orders, billing or customer records through properly configured integrations.
Higgs Avatar
Boson AI also develops AI avatar technology that adds a visual presence to conversational voice agents.
Higgs Avatar can create a talking face from a single still image and synchronize facial movement, expressions and lip movement with generated speech.
Avatar API
Developers can generate talking-head avatar videos from a still image combined with an audio recording or Higgs generated speech.
This can be useful for virtual assistants, educational content, customer experiences and other applications requiring a visual AI character.
Live Translation
Boson AI demonstrates a live translation use case where an AI interpreter listens to spoken conversation, understands it and translates it in real time.
This can support multilingual customer interactions and international communication.
Multi-Speaker Speech Generation
The Higgs family of TTS models supports multi-speaker dialogue generation.
This can be useful for conversational content, storytelling, podcasts, simulations and applications involving several AI characters.
Long-Form Audio Generation
Boson’s speech models are designed to maintain voice consistency during longer pieces of generated audio.
This can make the technology useful for narration, educational material and other long-form speech applications.
API Access
Developers can connect Boson AI’s models to their own applications through APIs.
This makes it possible to build custom voice agents, conversational products and automated business workflows rather than relying only on Boson’s demonstration interfaces.

Support for more than 100 languages in its latest real-time and TTS technologies makes the platform relevant for global applications.
Interruption handling is particularly important for natural voice conversations because people frequently interrupt, pause or change direction while speaking.
Voice cloning and detailed control over emotion, speed, pitch, pauses and speaking style provide developers with significant flexibility when designing voice experiences.
Tool calling makes it possible to connect conversational agents with real business workflows rather than limiting them to general conversation.
The combination of voice and avatar technology also gives developers the option to create AI experiences that communicate through both speech and visual expressions.
Drawbacks
Boson AI is primarily aimed at developers, businesses and technical teams rather than casual users who simply want an easy voice generator.
Building a production voice agent may require API integration, workflow configuration and software development knowledge.
Clear public pricing across every product and enterprise deployment option is not consistently presented, making it difficult to estimate total costs without reviewing API documentation or contacting the company.
Voice cloning also needs to be used responsibly. Developers should obtain appropriate permission before cloning or reproducing another person’s voice.
AI speech recognition and generated responses can still make mistakes. Business-critical applications should therefore include appropriate testing, monitoring and human oversight.
Some technologies and APIs may also have different availability stages, so developers should confirm current production status before building critical applications around them.
Comparison with Other Platforms
Boson AI operates in the rapidly growing conversational voice AI market alongside companies offering text-to-speech, speech recognition and real-time voice agent technology.
Its main distinction is its full-stack approach. Boson develops foundation audio models as well as the infrastructure needed to turn those models into production voice agents.
Compared with traditional text-to-speech platforms, Boson AI goes further by combining speech generation with speech understanding, real-time conversation, interruption handling and tool calling.
Compared with basic transcription services, Higgs STT is designed not only to recognize words but also to provide richer understanding of language and emotional signals.
The platform also combines voice with Higgs Avatar, allowing businesses to create visual conversational agents rather than voice-only experiences.
Some competing platforms may offer larger existing integration ecosystems, simpler no-code interfaces or more transparent self-service pricing. Boson AI may be more attractive to technical teams that want deeper control over the underlying voice and conversational experience.
