When to choose AMAI Voice?
AMAI Voice is the best option if you identify with any of these scenarios.
You need a complete solution, not just an API
Retell AI gives you the pieces to build. AMAI Voice provides the finished product: voice agents, telephony, billing, and dashboard all in one platform. Set up your agent and start receiving calls in minutes, without writing a single line of code.
Your market speaks Spanish
AMAI Voice is optimized for Spanish from Spain and Latin America, with voice models adjusted for regional accents, technical support in Spanish, and a user experience designed for the Spanish-speaking market. Retell AI focuses on the Anglo-Saxon market.
You want integrated telephony without third parties
With AMAI Voice, you don’t need to hire Twilio or any other external telephony provider. The FreeSWITCH infrastructure with integrated SIP Trunk gives you complete control over your lines, numbers, and call routes from a single dashboard.
You are looking for white-label for your brand
AMAI Voice allows distributors and agencies to offer the platform under their own brand. Ideal for telecommunications companies, tech consultancies, and agencies that want to add AI voice to their catalog without developing from scratch.
When to choose Retell AI?
Let's be fair: Retell AI is a great tool in certain scenarios.
You are a developer and latency is your priority
If your technical team needs to build an ultra-fast and personalized voice experience, Retell AI stands out for its low latency and well-documented API. Its developer-first approach allows granular control over every aspect of the voice conversation.
You want to integrate voice AI into your own product
If you already have an application or platform and just need to add conversational voice capabilities as a component, Retell AI's API-first approach may fit well. You have your own dashboard, billing, and telephony, and just need the voice engine.
The fundamental difference: API vs Platform
The decision between AMAI Voice and Retell AI boils down to one key question: Do you need to build or do you need to use?
Retell AI provides an excellent voice engine with low latency and a clean API. But you will need to build the rest: the management interface, the telephony connection (usually via Twilio), the billing system, multi-language support, and the business logic around calls. This requires a development team and weeks or months of integration.
AMAI Voice gives you all that already built. It includes an AI switchboard with its own FreeSWITCH and SIP Trunk infrastructure, a multi-tenant management dashboard, billing with Stripe and wallet, and configurable AI voice agents without code. All optimized for companies operating in Spanish.
If you are a technical team looking to integrate voice AI as a component within an existing product, Retell AI is a solid option. If you need a complete solution to handle calls with AI right now, AMAI Voice is the most direct and efficient alternative.
