WHY TELNYX?
Everything Voice AI needs on one platform
Skip the multi-vendor complexity. Telnyx handles infrastructure end-to-end—you, so you can focus on the customer experience.
Cost-effective AI agents
Telnyx pricing for base rate is budget friendly. Need more volume? Committed-use discounts on STT and TTS lower your costs further as you scale. No surprise add-ons for telephony, no per-seat fees, no middlemen taking a cut.
Speech-to-text
Telnyx gives you access to multiple STT engines, such as Deepgram, Google, Azure, and our own engine, so you can pick the best fit for your language, accuracy, or cost needs. Switch providers anytime without rebuilding your stack. When a better model comes out, swap it in.
Text-to-speech
Access ElevenLabs, Azure Neural, AWS, MiniMax, ResembleAI, Telnyx NaturalHD and Ultra, and other leading engines. Over 100 languages and variants mean you can reach more customers in their native language and respond faster in any market. Switch providers anytime without rebuilding. No lock-in, no migration headaches.
One-click telephony integration
Telnyx is a licensed carrier with local numbers in 140+ countries. Purchase a number and assign it to your AI agent instantly. No third-party telephony provider to configure, no extra contracts, no integration headaches. Your agent is live on the PSTN in minutes.
Low-latency voice
Most voice AI stacks route calls through 4 to 5 separate providers, including telephony, STT, LLM, TTS, orchestration, adding latency at every hop. Telnyx runs everything on one network. Audio enters, gets processed, and returns without leaving our infrastructure. The result: sub-200ms round-trip times that keep conversations natural.
Noise suppression
Crystal-clear audio is the foundation of great customer experience. Telnyx noise suppression and HD Voice codecs filter out background noise before it reaches your agent, so conversations feel natural, and customer names, account numbers, and key details are captured accurately the first time.
Context-rich conversations
Give your Voice AI Agent access to custom tools and over 30 pre-built integrations across 13 categories, including Salesforce, HubSpot, ServiceNow, Calendly, Jira, and more. Pull customer data into calls, trigger actions in real time, and personalize every conversation with live context.
