# Do coding agents recommend Azure Voice Live API? > Azure Voice Live API was chosen in 3% of 308 judged voice agents sessions, ranking seventh. Measured with Claude Code, Codex and Cursor. Source: https://armature.tech/library/do-coding-agents-recommend-azure-voice-live-api Published: 2026-09-03 Publisher: Armature, Inc. (https://armature.tech) --- > Azure Voice Live API was chosen in 3% of 308 judged voice agents sessions, ranking seventh. It was also raised as a candidate in 2 further sessions without being chosen. This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in voice agents inside a realistic codebase. Not what a chat assistant says about Azure Voice Live API. What an agent actually installed. One thing to read first: every one of those wins came from a **single codebase**. That is a result about one repository rather than about voice agents in general, and the splits below cannot separate the two. Treat them as a description of that repository. ## The numbers | | | | --- | --- | | Category | Voice agents | | Sessions in the category | 308 | | Sessions where Azure Voice Live API was chosen | 10 | | Install share | 3% | | Rank in category | 7 of 18 | | Codebases it won in | 1 | | Raised as a candidate, not chosen | 2 | | Chosen when considered | 83% | | Site | azure.microsoft.com | ## By agent With 10 wins spread across three agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established. | Agent | Sessions | Chose Azure Voice Live API | Share | | --- | --- | --- | --- | | Claude Code | 94 | 1 | 1% | | Codex | 110 | 7 | 6% | | Cursor | 104 | 2 | 2% | ## By who was asking Azure Voice Live API performs similarly across the four kinds of buyer, from 0% to 13%. That is unusual: the category leader changed with the persona in 14 of the 18 categories we measured. | Who is asking | Sessions | Chose Azure Voice Live API | Share | | --- | --- | --- | --- | | Vibe coder | 62 | 0 | 0% | | Junior developer | 42 | 0 | 0% | | Senior engineer | 128 | 0 | 0% | | Enterprise team | 76 | 10 | 13% | ## What Azure Voice Live API was up against The full ranking in voice agents, from the same sessions: | # | Product | Runs won | Share | | --- | --- | --- | --- | | 1 | Vapi | 74 | 24% | | 2 | Retell AI | 55 | 18% | | 3 | OpenAI Realtime API | 37 | 12% | | 4 | LiveKit Agents | 35 | 11% | | 5 | ElevenLabs Agents | 30 | 10% | | 6 | Twilio ConversationRelay | 28 | 9% | | 7 | Built in-house (no product adopted) | 18 | 6% | | 8 | Azure Voice Live API **(this page)** | 10 | 3% | ## What this means Agents almost never raise Azure Voice Live API without choosing it: 2 sessions raised against 10 chosen. When it gets considered, it usually wins. The constraint is how rarely it gets considered at all, which is a presence problem: templates, framework integrations and pages that answer the configuration and production questions agents actually search for. ## Where these numbers come from The 308 sessions in voice agents are part of a published set of 5,292, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: [how we measured this](/library/how-we-measured-this). Every voice agents run can be replayed on [the board](/leaderboards/voice-agents). If you work on Azure Voice Live API: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts. ## Common questions ### Do coding agents recommend Azure Voice Live API? Yes. Azure Voice Live API was chosen in 10 of the 308 judged sessions in voice agents, a 3% install share, ranking seventh in its category. ### Does Claude Code recommend Azure Voice Live API? In 1 of the 94 sessions in voice agents run with Claude Code, which is 1%. ### Do different coding agents treat Azure Voice Live API differently? Not much. The three agents chose it at similar rates, between 1% and 6% of their runs. ### How was this measured? Real coding agents at pinned versions were run in sandboxes inside 51 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind. ### How often is Azure Voice Live API considered but not chosen? It was raised as a candidate in 2 sessions without being chosen, and chosen in 10. That is a 83% conversion from considered to chosen. ## Read next - [How to get picked for voice agents by coding agents](https://armature.tech/library/voice-agents-coding-agents-playbook) (Markdown: https://armature.tech/library/voice-agents-coding-agents-playbook.md) - [Do coding agents recommend Vapi?](https://armature.tech/library/do-coding-agents-recommend-vapi) (Markdown: https://armature.tech/library/do-coding-agents-recommend-vapi.md) - [Do coding agents recommend Retell AI?](https://armature.tech/library/do-coding-agents-recommend-retell-ai) (Markdown: https://armature.tech/library/do-coding-agents-recommend-retell-ai.md) - [Do Claude Code, Codex and Cursor pick the same tools?](https://armature.tech/library/do-claude-code-and-codex-agree) (Markdown: https://armature.tech/library/do-claude-code-and-codex-agree.md) --- Armature helps software products get discovered and used by coding agents.
