Vapi

Meet ai-coustics, a Berlin-based deep-tech company building the audio intelligence layer for Voice AI.

Rather than competing with ASR, LLMs, or TTS, ai-coustics helps make them more reliable in real-world environments. Its SDK spans real-time speech enhancement and isolation, voice activity detection, and audio-quality risk scoring—helping teams diagnose and prevent the audio issues that cause voice systems to fail.

Powering voice agents, transcription pipelines, and telephony systems across Europe and North America, ai-coustics is helping set a new standard for Voice AI reliability.

Come meet the ai-coustics team at #VapiCon2026!

You can put a Vapi assistant almost anywhere

GPT-Live is now in beta for every builder in Vapi .

OpenAI's full-duplex speech-to-speech model, live on Vapi. One model listens and talks at once. A reasoner runs your tools and skills in the background. Faster turns, cleaner interruptions, better accuracy on names and numbers.

@AssemblyAI new model, Universal 3.6 Pro is live on Vapi.

Most voice agent failures start at transcription. 3.6 Pro makes 45% fewer wrong yes/no confirmations, cuts background speech in transcripts by 30%, and holds the turn until it has the full phone number, code, or email. Plus 14 new languages with mid-sentence code-switching.

Switch your agents in the dashboard: dashboard.vapi.ai

Have your personal AI assistant make the call you keep putting off.

Vapi Personal Assistant Calling is now in beta. Free to try and works with Muse, Instinct, GrokBot, ChatGPT Work, Claude Code, OpenClaw, and Hermes.

One of our team members had his assistant call an airline to upgrade his seat. 14 minutes on hold, fee waived, confirmation texted back, while he kept working.

Paste this into your assistant:

"Open phone.vapi.ai, read the agent instructions, and call [business + location] to [task]."

We’re excited to welcome Hamming AI as a Startup Sponsor of VapiCon 2026!

Hamming AI is the trust and reliability platform for teams deploying voice and chat agents. Before launch, Hamming runs realistic and adversarial conversations to find where agents break. In production, it monitors how agents perform with real users. When a failure is found, teams can turn it into a regression test and rerun it after every prompt, model, or workflow change.

Hamming simulates accents, languages, background noise, interruptions, edge cases, and social-engineering attacks. It evaluates conversation quality, latency, tool calls, handoffs, and compliance—creating a continuous reliability loop that helps teams find new weaknesses and verify that fixes still work.

Join us November 11–12 at Fort Mason in San Francisco as the voice AI community connects, builds, and launches what’s next.

Please join us in welcoming Neil Zeghidour, Co-founder CEO of @GradiumAI, as a Speaker at VapiCon 2026!

Neil founded Gradium after a decade of building and leading frontier generative audio teams at Meta and Google DeepMind. Being frustrated by slow and brittle voice assistants, he built the engineering teams that developed the first neural audio codecs and introduced the first audio LLMs, such as AudioLM, at Google. He later created Kyutai to launch Moshi, the world's first real-time, full-duplex conversational AI, and Hibiki, the first simultaneous speech-to-speech translation system. Today, Gradium is focused on helping developers build natural, real-time voice agents by providing ultra-low latency streaming APIs that transition these breakthroughs from the research lab to production.

Join us in San Francisco this November as Neil and more industry leaders come together to delve into the future of Voice AI.

"We know speed wins, and if we can deliver a candidate to a client faster, they're always willing to pay more for it." - Ronak Shah, co-founder and CEO of Ancile Services.

Their best-case human response time was 18 hours. On Vapi, it's 2.5 minutes, across 250K calls per month.

You changed one line in the prompt.
You have no idea what else was affected.

A voice agent can answer the same caller three different ways. One good test call isn't evidence you can depend on for production.

Swipe to learn best practices for testing voice agents so you can be confident every update works.
