What is Sonalyx?
Sonalyx is a SaaS platform for phone surveys that uses conversational artificial intelligence agents to conduct interviews. Unlike the robotic IVR systems of the past, Sonalyx agents maintain natural conversations, as if they were human survey researchers.
The platform is specifically designed for demographic studies, market research, and opinion surveys. It includes features such as:
- Architect Agent: Upload a PDF with your questionnaire and AI automatically converts it into an interview flow
- 1,000 simultaneous agents: Massive scale without staffing limitations
- Real-time Dashboard: See results as calls are in progress
- Multilingual: Works in any country and language
The pricing model is based on cost per minute of conversation, with no fixed costs or commitments.
The Traditional CATI Model and Its Limitations
Traditional CATI call centers (Computer-Assisted Telephone Interviewing) have been the only available option for professional phone surveys for decades.
The traditional model requires:
- Expensive human operators
- Physical infrastructure: offices, equipment, phone lines
- Complex management: shifts, training, constant supervision
- Limited hours: only operate during business hours
- Slow scalability: hiring and training new operators takes weeks
The result: high costs, long execution times, and limited capacity that cannot grow on demand.
These structural limitations of the traditional model are exactly what Sonalyx solves with conversational AI technology.
Detailed Comparison: 6 Key Criteria
1. Cost Per Interview
This is probably the most important difference.
Sonalyx: Pay-per-minute model with no fixed costs or infrastructure. You only pay for the actual time of each interview.
CATI Call Centers: Costs include operator salaries, physical infrastructure, supervision, training, and operational margins. Each interview bears all these structural costs.
Verdict: Sonalyx offers 70-85% savings in direct costs by completely eliminating personnel costs and physical infrastructure.
2. Execution Speed
Sonalyx: A campaign of 1,000 surveys can be completed in 24-48 hours. AI agents can make simultaneous calls 24 hours a day, 7 days a week.
CATI Call Centers: The same study can take 2-4 weeks. Operators have limited hours, breaks, and can only make one call at a time each.
Verdict: Sonalyx is between 10x and 20x faster. This is critical for voting intention studies, brand tracking, or any research where speed matters.
3. Scalability
Sonalyx: Can instantly scale to 1,000 simultaneous agents. If you need 10,000 surveys, there’s no significant operational difference compared to 1,000.
CATI Call Centers: Scalability is limited by available staff. Getting 50 additional operators for a large project involves hiring, training, and coordination.
Verdict: Sonalyx wins clearly. AI architecture enables elastic scale without the friction of the physical world.
4. Conversation Quality
To be honest, humans still have an advantage in complex situations.
Sonalyx: Next-generation AI agents maintain very natural conversations. They can handle open-ended responses, improvise clarifications, and adapt to the respondent’s tone. However, in very complex or emotionally sensitive situations, they may fall short.
CATI Call Centers: Experienced human operators can handle any situation, detect emotional nuances, and adapt their approach in real time. For in-depth interviews or sensitive topics, they remain superior.
Verdict: Technical tie. For standard structured surveys, AI is sufficiently good. For deep qualitative research, humans are still better.
5. Consistency and Quality Control
Sonalyx: Each AI agent follows exactly the same protocol, with the same tone, 24 hours a day. There’s no variability between operators, no “bad days,” no different interpretations of the script.
CATI Call Centers: Quality depends on the individual operator. It requires continuous supervision, call listening, and deviation correction. Even with good oversight, there’s natural variability between people.
Verdict: Sonalyx wins on consistency. When you need 1,000 interviews conducted exactly the same way, AI is more reliable.
6. Flexibility and Configuration
Sonalyx: Configuring a new campaign can be done in minutes with Architect Agent. You upload the questionnaire, define parameters, and launch. Changes apply instantly to all agents.
CATI Call Centers: Setting up a new study requires programming CATI software, training operators on the specific questionnaire, running pilot tests, and adjusting. Can take days or weeks.
Verdict: Sonalyx is significantly more agile for launching and adjusting studies.
Comparison of Economic Models
Sonalyx Pricing Model
Sonalyx operates with a pay-as-you-go model based on effective conversation time:
- No setup costs
- No minimum commitments
- Pay only for actual conversation
- Volume discounts available
- No infrastructure or personnel costs
CATI Call Center Pricing Model
Traditional call centers have a complex cost structure:
- Cost per completed interview (includes multiple components)
- Operator rates + supervision + infrastructure
- Fixed costs independent of volume
- Significant operational margins
Who Offers the Best Value?
For most standard quantitative studies, Sonalyx offers 80-90% savings with comparable quality. The difference is so significant that it enables studies that were previously prohibitive due to budget constraints.
Who is Sonalyx Best For?
Sonalyx is the best option if you:
- ✅ Need quick results (days, not weeks)
- ✅ Have a limited budget or want to maximize sample size
- ✅ Conduct structured surveys with mostly closed-ended questions
- ✅ Need massive scale (thousands of interviews)
- ✅ Want total consistency between interviewers
- ✅ Operate in multiple countries/languages
- ✅ Need 24/7 availability (different time zones)
Who Are Traditional CATI Call Centers Better For?
Traditional call centers may be the better option if you:
- ✅ Conduct in-depth qualitative research with extensive open-ended questions
- ✅ The topic is emotionally sensitive and requires human empathy
- ✅ Need complex improvisation during the interview
- ✅ Your target audience is elderly people who may prefer human interaction
- ✅ You already have an established relationship with a trusted provider
- ✅ Budget is not a significant constraint
What We Acknowledge About CATI Call Centers
To be fair, traditional call centers have real strengths:
- Decades of experience: They have perfected methodologies over years
- Human flexibility: They can handle any unexpected situation
- Established credibility: Some clients trust “real people” more
- Qualitative research: For in-depth interviews, they remain the standard
We’re not saying CATI call centers are bad. They’ve been the backbone of market research for decades, and for certain use cases they remain valid.
Where Sonalyx Clearly Excels
That said, Sonalyx has advantages that traditional call centers simply cannot match:
Unmatched Speed
Launching weekly brand tracking is unfeasible with call centers (cost and time). With Sonalyx, it’s routine.
Democratization of Research
Studies that only large companies could do due to budget constraints are now accessible to SMEs and startups.
Perfect Consistency
You eliminate the negative human factor (fatigue, interpretation, variability) while maintaining conversational naturalness.
Instant Scalability
From 100 to 10,000 surveys without changing anything operationally.
Continuous Innovation
AI technology improves constantly. Today’s agents are better than those from 6 months ago, and those in 6 months will be even better.
Final Verdict: Sonalyx is the Evolution of CATI
For 90% of quantitative studies—market surveys, political studies, customer satisfaction, opinion research—Sonalyx offers a decisive competitive advantage.
Sonalyx’s conversational AI technology has reached the maturity necessary to match the quality of human interaction, but with advantages that no traditional call center can offer:
✅ 80% cost savings ✅ 20x faster in execution time ✅ Unlimited scalability (1,000 simultaneous agents) ✅ Perfect consistency in each interview ✅ 24/7 availability in any time zone
The Decision is Clear
Choose Sonalyx if you want to:
- Maximize ROI with costs up to 85% lower

Sonalyx is not just cheaper and faster: it’s the natural evolution of CATI for the AI era. Leading companies are already making the switch.
Frequently Asked Questions
Is Sonalyx really cheaper than a call center?
Yes, significantly. Typical savings are 70-85% in direct costs. This is because AI agents don’t have salaries, don’t need offices, don’t take breaks, and can operate 24/7. You completely eliminate personnel costs, infrastructure, and supervision costs.
Do respondents notice they’re talking to AI?
Sonalyx AI agents use next-generation conversational voice technology. Most respondents cannot distinguish that they’re speaking with AI, especially in structured surveys. Response rates are comparable to human operators.
Can I migrate my current call center studies to Sonalyx?
Yes, it’s simple. Upload your current questionnaire (in PDF or Word) and Architect Agent automatically converts it into an interview flow for AI agents. You can run a pilot test to compare results before fully migrating.
What if the respondent asks an unexpected question?
Sonalyx AI agents are trained to handle deviations naturally. They can clarify questions, repeat statements, and guide the conversation back to the questionnaire. For very complex situations, they can transfer the call or flag it for review.
Does Sonalyx work for political surveys and voting intention polls?
Yes, it’s one of the main use cases. Execution speed (results in hours) is especially valuable for electoral tracking where data currency is critical. Several voting intention studies are already conducted using conversational AI technology.
Which has a better response rate?
Response rates are comparable. Some studies show even better rates with AI because respondents don’t feel social pressure from interacting with a human and are more honest in their responses.
