Alternatives include Listen Labs (enterprise scale), Strella (consumer panel), Outset (video artifacts), Conveo, Glaut, Perspective AI, and TheySaid. Voice responses run about 3x longer, capture ~67% more emotional nuance, and achieve up to 70% higher completion than email or SMS surveys.","content":"# Best Voice Survey Software in 2026 (Top 8 Tools Compared)\n\n**Answer first:** The best voice survey software in 2026 is **Koji**, because it pairs AI-moderated voice interviews with six structured question types, automatic thematic analysis, and one-click reports — starting at €29/month with 10 free credits. Strong alternatives include Listen Labs, Strella, Outset, Conveo, Glaut, Perspective AI, and TheySaid, each suited to specific use cases covered below.\n\nVoice is taking over feedback for a simple reason: people say more out loud than they type. Spoken responses are roughly **3x longer than text answers**, capture about **67% more emotional nuance**, and achieve **up to 70% higher completion rates** than email or SMS surveys. With **email survey response rates often falling below 5%**, voice surveys are how modern teams get depth *and* scale at once. This guide ranks the eight platforms worth evaluating in 2026.\n\nFor the methodology behind voice surveys, see our [complete guide to AI voice surveys](/docs/ai-voice-surveys-complete-guide).\n\n## What makes voice survey software \"good\" in 2026\n\n- **A real AI moderator** that asks adaptive follow-up questions, not just a recorded prompt.\n- **Structured + open questions in one study** so you get quantitative and qualitative data together.\n- **Automatic analysis** — transcription, themes, and quotes without manual coding.\n- **Transparent pricing** that does not require an enterprise contract to get started.\n- **Low participant friction** — no app install, works over a browser link.\n\n## 1. Koji — best overall voice survey + AI interview platform\n\nKoji is the AI-native customer research platform built for founders, PMs, agencies, and lean research teams. Its AI consultant designs the study, runs **AI-moderated voice interviews** (powered by ElevenLabs) with adaptive probing, and then performs **automatic thematic analysis** to deliver a **one-click report**. What sets Koji apart is breadth in a single study: **six structured question types — open-ended, scale, single choice, multiple choice, ranking, and yes/no** — so one voice study captures ratings *and* the story behind them.\n\n- **Best for:** Teams that want moderated-interview depth at survey scale without hiring a moderator.\n- **Pricing:** €29/month (Insights) or €79/month (Interviews); 10 free credits; voice interviews cost 3 credits, and only conversations passing the quality gate are billed.\n- **Why it leads:** End-to-end — design, moderate, analyze, report — with no moderator bias and transparent pricing. Explore [survey question types](/docs/survey-question-types) and [reading your research report](/docs/reading-your-research-report).\n\n## 2. Listen Labs — voice surveys at enterprise scale\n\nListen Labs handles voice surveys at scale and combines interviews with automated personas, thematic insights, and reports in hours. It is a strong fit for larger market research programs that need high participant volume.\n\n- **Best for:** Enterprise market research teams running high-volume studies.\n- **Limitation:** Enterprise-oriented; less transparent entry pricing for small teams. See [Koji vs Listen Labs](/blog/koji-vs-listen-labs-2026).\n\n## 3. Strella — rapid consumer research over voice and video\n\nStrella offers rapid AI-moderated research with a reported 90% NPS, a 3M+ consumer panel, and theme synthesis in minutes. It is built for fast consumer studies across voice and video.\n\n- **Best for:** Consumer brands needing a built-in B2C panel and quick turnarounds.\n- **Limitation:** No native text modality and seat-based enterprise pricing. See [Koji vs Strella](/blog/koji-vs-strella-2026).\n\n## 4. Outset — video-and-voice for UX and product teams\n\nOutset focuses on AI-moderated video and voice interviews for UX and product research, producing standardized interview artifacts.\n\n- **Best for:** Teams that want consistent video interview deliverables.\n- **Limitation:** Reported gaps in recruitment and fraud prevention, and a mobile app that has been Android-only — a constraint for iOS-heavy audiences. See [Koji vs Outset](/blog/koji-vs-outset-2026).\n\n## 5. Conveo — conversational AI interviews\n\nConveo runs AI-moderated conversational interviews with a focus on natural dialogue and qualitative depth, aimed at research and insights teams.\n\n- **Best for:** Insights teams prioritizing conversational qualitative depth.\n- **Limitation:** Narrower structured-question support than Koji. See [Koji vs Conveo](/blog/koji-vs-conveo-2026).\n\n## 6. Glaut — voice-first open-ended research\n\nGlaut is a voice-first platform for open-ended research that automates probing and analysis, popular for fast qualitative reads.\n\n- **Best for:** Quick open-ended qualitative studies.\n- **Limitation:** Less emphasis on mixing structured question types in one study. See [Koji vs Glaut](/blog/koji-vs-glaut-2026).\n\n## 7. Perspective AI — voice of customer across channels\n\nPerspective AI positions itself around conversational voice-of-customer, ranking platforms by listening depth and channel coverage.\n\n- **Best for:** VoC programs combining multiple listening channels.\n- **Limitation:** Broader VoC focus rather than a self-serve research tool for product teams.\n\n## 8. TheySaid — AI voice surveys for CX and feedback\n\nTheySaid offers AI-driven voice surveys focused on conversational customer feedback and experience measurement.\n\n- **Best for:** CX teams replacing static NPS/CSAT forms with conversations.\n- **Limitation:** Feedback-survey orientation rather than full research-study design.\n\n## Quick comparison table\n\n| Tool | Best for | AI-moderated voice | Structured + open in one study | Starting price |\n|---|---|---|---|---|\n| **Koji** | All-round research depth at scale | Yes | Yes — 6 question types | €29/mo · 10 free credits |\n| Listen Labs | Enterprise market research | Yes | Partial | Enterprise |\n| Strella | Consumer research + panel | Yes | Limited (no text mode) | Enterprise (seat-based) |\n| Outset | Video interview artifacts | Yes | Partial | Custom |\n| Conveo | Conversational qual depth | Yes | Partial | Custom |\n| Glaut | Fast open-ended studies | Yes | Limited | Custom |\n| Perspective AI | Multi-channel VoC | Yes | Partial | Custom |\n| TheySaid | CX feedback surveys | Yes | Limited | Custom |\n\n## How to choose\n\nIf you are an enterprise market research org with high volume, Listen Labs or Strella are credible. If you need standardized video deliverables, look at Outset. But if you want one tool that **designs the study, moderates the voice interview, mixes six structured question types, and analyzes everything into a one-click report** — at a price a startup or small team can actually start on — Koji is the clear pick. For the methodology, read our [AI voice surveys guide](/docs/ai-voice-surveys-complete-guide); for the broader category, see the [best AI customer interview tools](/blog/best-ai-customer-interview-tools-2026) and [AI-moderated interview platforms](/blog/ai-moderated-interview-platforms-2026).\n\n## Why voice beats static forms (the data)\n\n- **3x longer responses** than typed answers — more signal per participant.\n- **Up to 70% higher completion** than email or SMS surveys.\n- **~67% more emotional nuance** captured versus text.\n- Against a backdrop where **email survey response rates frequently dip below 5%**, voice is how you keep getting answers at all.\n\nThe takeaway: static surveys are hitting a wall, and AI-moderated voice is where serious research is heading. The user research software market alone is projected to grow from roughly **$2.41 billion in 2026 to $4.12 billion by 2035**, with conversational AI as the highest-growth lane.\n\n## Get started with Koji free\n\nReady to hear what your customers actually think?

A voice survey uses conversational AI to ask questions aloud, listen to spoken answers, and ask adaptive follow-ups. Voice responses are about 3x longer, capture roughly 67% more emotional nuance, and reach up to 70% higher completion than email or SMS surveys.","question":"How is a voice survey different from a regular survey?"},{"answer":"For depth, yes. With email survey response rates often below 5% and survey fatigue rising, AI-moderated voice gets longer, richer answers and higher completion. Static forms still work for very short, transactional questions, but voice surveys deliver the why behind the numbers at survey scale.","question":"Are voice surveys better than static forms?"},{"answer":"It varies widely. Many enterprise voice platforms use custom or seat-based pricing. Koji is transparent and self-serve, starting at €29/month (Insights) or €79/month (Interviews), with 10 free credits to start; a voice interview costs 3 credits and only conversations that pass the quality gate are billed.","question":"How much does voice survey software cost?"},{"answer":"The best tools do.
