Voice AI platforms: AI search visibility ranking (2026)
How AI search engines rank voice ai platforms by visibility and citations. 20 brands measured monthly across Google AI Mode: which brands the AI names in answers, which domains it cites as sources, and how the leaders compare. Voice AI platforms used to synthesize speech, run conversational agents, transcribe calls, and build real-time voice experiences into products and workflows. Composite score: 70% visibility (% of AI answers naming the brand) + 30% citation rate (% citing the brand's domain). Full methodology →

At a glance
What we observed in this categoryauto-generated
Retell AI leads the Voice AI platforms category with a visibility score of 37.5%, more than 12 percentage points clear of the three brands tied at 25% (Vapi, Bland, and ElevenLabs). Its composite score of 48.8 is more than double any competitor, and the category average visibility sits at just 5.6%, meaning Retell AI appears roughly 6.7 times more often than the typical brand in this set. That gap signals a highly concentrated AI visibility landscape where one brand captures a disproportionate share of Google AI Mode responses.
ElevenLabs presents the clearest divergence between visibility and citation in this dataset. It matches Vapi and Bland on visibility at 25%, yet carries a 0% citation rate compared to their 12.5% each. Retell AI shows the opposite dynamic: its citation rate of 75% far exceeds its 37.5% visibility, suggesting AI Mode trusts it as a source even beyond the queries where it names the brand. Hume AI, Cartesia, PlayHT, Deepgram, AssemblyAI, and Rime all record zero on both metrics.
Google AI Mode is the dominant engine across every brand in this category, with no outliers recorded. The top cited sources include youtube.com, retellai.com, vellum.ai, ringly.io, zapier.com, voice.ai, vapi.ai, and lindy.ai. The presence of third-party aggregator and workflow sites (Zapier, Vellum, Lindy, Ringly) alongside brand-owned domains indicates that AI Mode anchors on comparison and tutorial content rather than relying solely on official brand pages when generating Voice AI platform responses.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer.
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence — different from being named.
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps.
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically.
