Voice AI
Voice AI · Human-Parity French Voices
A Voice So Natural, It’s Indistinguishable From a Human.
Voice AI by Amalya IA designs vocal agents that answer calls, engage in conversation, ask the right questions, and trigger concrete actions—bookings, quotes, transfers, or lead qualification. For both inbound and outbound calls.
Natural French voice · Latency under 800ms · GDPR-compliant & recordings in France · ElevenLabs · OpenAI · Cartesia
Voice AI consists of conversational vocal agents capable of holding a real phone discussion. Not an answering machine. Not an IVR (“press 1 for sales”). An agent that understands phrases like “I’d like to reschedule my Tuesday appointment to Thursday at 2 PM” and executes the request.
Since 2024, voice synthesis quality has skyrocketed. ElevenLabs, OpenAI Voice, and Cartesia models generate natural French voices—complete with breathing, hesitations, and intonation. Latency under 800ms—the agent responds as quickly as a human on the phone.
At Amalya IA, we build custom Voice AI agents: AI Receptionist, inbound qualification, outbound prospecting, surveys, follow-ups. We leverage Vapi, Retell AI, Bland AI, or self-hosted n8n—depending on your sovereignty requirements.
For whom
Practical applications of Voice AI
Inbound, outbound, surveys, follow-ups—a vocal agent for every use case.
Call reception
A AI Receptionist that answers, qualifies, schedules appointments, and transfers urgent calls. Available 24/7, multilingual, and never overwhelmed.
Outbound prospecting
A vocal agent that calls your prospects, presents your offer, qualifies interest, and schedules a meeting with your sales team—only if the prospect is warm.
Surveys & feedback
Automated post-purchase or post-service calls to collect vocal feedback. Far higher response rates than email—people are more willing to engage with a voice.
Payment follow-ups
Polite and personalized overdue payment follow-ups. The AI listens to the reason for the delay, proposes a payment plan, processes card payments over the phone, or schedules a callback.
Appointment confirmations
Vocal follow-ups 24 hours before an appointment (medical, restaurant, service). The AI detects if the client wants to cancel or reschedule and updates the calendar in real time.
B2B lead qualification
Before involving a sales rep, the AI calls leads to qualify interest, budget, and decision-making authority. Only genuine leads are escalated to your team.
Method
How we build your Voice AI agent
5 steps, from script to production-ready vocal agent.
01
Use case audit (30 min)
We define the precise objective: inbound qualification, outbound prospecting, survey, or follow-up. We quantify the stakes (number of calls, expected ROI).
Deliverable: Vocal agent specifications
02
Voice selection
We test 5–10 French voices (ElevenLabs, OpenAI Voice, Cartesia). We choose the tone, pace, and gender. Option to clone your voice for premium use cases.
You approve the voice before development begins
03
Conversational script writing
We draft a branching script: opening line, qualification questions, objection handling, transfer conditions. The agent follows the script but remains flexible for unexpected responses.
Script versioned and approved word-for-word
04
Development & integrations
We configure the agent on Vapi, Retell, or Bland AI. We connect your CRM, calendar, and helpdesk. We set up the inbound or outbound number.
Compatible with your existing tech stack
05
Real-world testing
Testing phase with 30–100 live calls and continuous adjustments. Once the satisfaction rate is validated, the agent goes fully live.
30-day satisfaction guarantee

FAQ
Frequently asked questions about Voice AI
What’s the difference between a traditional IVR and a Voice AI agent?
An IVR ("press 1, press 2") is a rigid menu—if you deviate from the script, it fails. A Voice AI agent understands natural language: a phrase like *"I’d like to move my Tuesday appointment to Thursday around 2 PM"* is executed directly. The difference between a menu robot and a real vocal assistant.
Is the voice truly undetectable?
For short calls (under 3 minutes), most callers don’t detect the AI. On longer calls, some may suspect, especially if they ask highly unexpected questions. Our recommendation: disclose the AI nature upfront—transparency is increasingly valued and doesn’t impact conversion rates for most use cases.
What’s the latency between human speech and the AI’s response?
Between 600ms and 900ms, depending on question complexity. Faster than a human in most cases—the AI doesn’t need to process meaning, just generate a response. Natural conversation flow is preserved.
Which platforms do you use for vocal agents?
Depending on needs: Vapi for simplicity, Retell AI for advanced cases, Bland AI for high-volume outbound, self-hosted n8n for sovereignty. For voices: ElevenLabs, OpenAI Voice, Cartesia. For LLMs: OpenAI, Claude, Mistral. We select the stack that fits your use case.
Are my data and calls stored abroad?
Configurable based on your needs. By default, AI providers are European or use European servers with GDPR commitments. For sensitive cases (healthcare, legal, finance), we deploy a 100% French stack with self-hosted Mistral—no data leaves your server.
Can I clone my voice or a colleague’s?
Yes, technically possible with 3–5 minutes of voice recording. For ethical and legal reasons, we only do this with explicit written consent from the person. Often relevant for premium use cases (luxury hotels, private clinics).
What’s the cost per call?
Between €0.15 and €0.80 per call, depending on average duration. Cost includes: synthesized voice + speech recognition + LLM + call time. For short calls (under 2 minutes), around €0.30. Compared to €4–€12 for a human call, the difference is substantial.
How long does it take to deploy a vocal agent?
7 days for Starter (simple script, single channel), 14 days for Business (multi-branch + CRM), 21 days for Senior (multi-agents + custom integrations). The voice is ready in 24 hours; the rest of the time is spent on script writing and testing.
