With agentic voice experiences, interactions with AI agents are finally as fast and dynamic as a face-to-face conversation.

SoundHound AI’s Amelia platform now processes and comprehends speech in real time, streaming voice through a single, low-latency model, all while orchestrating highly capable AI agents in the background that get things done for users.

Responses are immediate, adapt to interruption, and reason in parallel to complete users’ requests. Now, you can really talk to AI like it’s any other person, and not be left hanging.

In much of automated customer service, voice interactions still feel like the past. Callers wait through long prompts, listen to rigid menus, and repeat themselves when legacy IVR or older simple voice bots get lost. Every extra second of silence makes it harder to keep customers engaged and contained in self-service.

At the same time, your customers already know what “good” sounds like: a natural, fast back-and-forth with a human who understands interruptions, corrections, and side questions.

Experience agentic voice AI in Amelia 7.3 — real-time conversations with AI agents that move at the pace and dynamics of human dialogue, while unlocking a new level of self-service.

Amelia listens, thinks, and speaks in parallel, so there’s no “wait and listen” feeling. Not only that, but users can jump in and interrupt at any moment, and Amelia adapts without losing context or missing a beat.

This is powered by our Speech-to-Meaning© model, plus rich controls for translation, voices, safety, and a new chat-style UI purpose-built for designing voice journeys. Together, they let you deliver fast, safe, truly conversational voice experiences across your highest-value channels.

Agentic voice AI: comprehension and action, not just speed

Agentic voice in Amelia is about more than fast responses. It’s a seamless combination of hearing, understanding, reasoning, and acting that behaves much closer to a skilled human. Amelia can: 

• Process speech, interpret meaning, and plan responses through a unified engine.
• Stream responses back while reasoning and task execution continue in the background.
• Let users interrupt at any moment, then smoothly pivot based on what they say next.
• Think critically about the caller’s request, develop creative solutions, and execute. 

This combination is ideal for CX and contact center leaders who need modern voice journeys that are just as capable as any mobile application or AI program.

Plus, the new agentic voice capability operates as a voice channel on top of Amelia’s existing agentic AI core. The same conversation flows, tools, and LLM integrations you use for chat or traditional voice now power real-time, streaming conversations across telephony, web, and in-app experiences.

Behind the scenes, platform-level resilience and observability improvements help keep these real-time journeys stable and debuggable as adoption grows.

Go ahead, interrupt 

In traditional systems, barge-in — which allows users to interrupt AI in the middle of a response — is either unsupported or fragile. Callers have learned not to talk until the automated system is done reading its script, because talking early usually leads to confusion or an error.

Now, there’s no more waiting for AI to finish its thought. With our new barge-in capability for voice, users can jump in the moment they’re ready. In fact, it’s encouraged. Amelia will pause, listen, and move to the next part of the conversation without missing a beat or losing context.

The result: faster, more natural conversations without the frustrating “sit and listen” experience from legacy voice automations.

Why barge-in matters

Most voice experiences still rely on a strict turn-taking model: the system talks, stops, records, processes, and then finally replies. That pattern introduces frustrating latency, “dead air,” and frequent misunderstanding — especially when customers try to move faster than the system can handle.

For high-volume customer service environments, those limitations show up as:

• Longer handle times and lower containment.
  
• Frustration from “please wait until the prompt has finished” constraints.
  
• Rigid menus that can’t adapt when customers change their minds mid-flow.
  
• Limited brand expression due to generic, robotic voices.

Agentic-enabled voice AI removes these pain points by giving callers a responsive, interruptible, and branded experience that feels as fast as a face-to-face conversation.

How Speech-to-Meaning© works in Amelia 7.3

Instead of treating speech recognition, language understanding, reasoning, and text-to-speech as disconnected stages, we bring them together into one tightly integrated flow.

SoundHound AI’s Speech-to-Meaning© approach continuously processes incoming audio, interprets intent, and plans the next step of the conversation. There’s no need to wait for a full transcription before understanding or acting.

For your teams, that means:

• A simpler mental model: one streaming voice capability, not a patchwork of services.
  
• Consistent behavior across journeys and channels.
  
• Fewer edge cases where partial phrases or mid-sentence changes derail the experience.

Parallel thinking and speaking

With the new streaming architecture, Amelia can think and speak at the same time. As soon as enough meaning is captured, Amelia begins to generate and stream response audio — even while back-end orchestration and reasoning continue.

This enables:

• A  low-latency voice experience that feels responsive and alive.
  
• Natural turn-taking, without long silences between steps.
  
• Faster completion of multi-step tasks, because users don’t feel compelled to “wait for their turn” before speaking up.

Multilingual capability now includes 40+ languages 

Amelia now speaks over 40 languages natively and can even speak them within the same conversation. Users can start a conversation in English, switch to Spanish, and then practice their French — all in the same breath. Amelia will detect the language without being prompted and speak it back in real time. 

And, no matter where your users are in the world, Amelia can understand. With additional customization, Amelia will learn any language you need.

A voice-focused UI update for AI agent builders

Voice is one of the most powerful parts of your brand experience. With Amelia 7.3 you gain significantly more flexibility in how Amelia sounds across user journeys.

Through integration with OpenAI TTS voices you can:

• Access 11 new high-quality voices with different tones and personalities.
  
• Mix and match voices per flow or use case (for example, a warm, reassuring support voice and a concise, energetic sales voice).
  
• Align voice tone with channel, region, or customer segment while keeping behavior consistent.

These text-to-voice features are managed via Admin UI controls, where teams can enable TTS, choose voices, and configure how they are applied to specific flows. Amelia 7.3 also includes a chat-style UI specifically optimized for building and testing real-time voice.

With this UI, designers and developers can:

• Test voice flows in a familiar chat interface with integrated audio.
  
• Observe how Amelia responds to interruptions, corrections, and edge cases.
  
• Validate guardrails, translations, and voice selection before rolling out to production.
  

This speeds up time-to-value and makes it easier for multi-disciplinary teams — CX leaders, conversation designers, and architects — to collaborate on voice journeys without needing specialized tools.

The bigger picture: agentic, voice-first, enterprise-grade

Agentic voice at human speed is a key step in Amelia’s broader vision: a platform where reasoning, orchestration, and voice interact seamlessly across channels.

It reinforces three pillars of the Amelia platform:

• Agentic AI: Amelia doesn’t just respond; it plans, acts, and adapts, using tools and integrations to complete real work on behalf of your customers and employees.
  
• Voice-first and omni-channel: Real-time streaming voice joins chat, messaging, and other channels as a first-class citizen in your automation strategy — not an afterthought.
  
• Enterprise readiness: Under the hood, platform resilience, logging, and integrations with multiple LLM providers help ensure that fast, natural voice is backed by the robustness large enterprises need.

As you evolve beyond traditional IVR or voice automation, Amelia gives you a single agentic platform that can handle both today’s high-volume calls and tomorrow’s more complex, multi-modal journeys.
