Research answer
No—based on the provided evidence, the claim is only partially supported. The evidence shows voice-related building blocks at xAI and a Tesla Grok integration, but it does not confirm that a model called “Grok 4.3” is a full voice assistant across Grok Voice, Tesla infotainment, and support surfaces.

What the evidence does support
- xAI’s release notes say its Speech-to-Text API is generally available and its Text-to-Speech API is generally available, which means xAI has official voice input and voice output capabilities at the API level. [
2]
- A Tesla 2025.26.4 release-notes tracking page says users can choose Grok’s voice and personality, launch Grok from the App Launcher, or long-press the steering-wheel voice button to launch it. [
6]
- That Tesla evidence supports some in-car voice interaction for Grok, but it does not, by itself, prove full hands-free assistant behavior across all driving and support contexts. [
6]
What the evidence does not prove
- The provided xAI evidence does not identify a model named “Grok 4.3.” [
1][
4]
- The only explicit Grok 4-series reference in the provided evidence is “Grok 4.20 Multi-Agent API” on xAI’s API page snippet, not “Grok 4.3.” [

- The provided evidence does not document an end-user product surface called “Grok Voice” or describe what features it has. [

2][
4]
- The provided evidence does not show Grok operating across “support surfaces,” such as customer support workflows, help desks, or agent-assist products. [
1][
2][
4]
- The provided Tesla material also does not show Grok controlling vehicle systems, replacing the native car assistant end to end, or handling support tasks. [
5][
6]
Evidence quality and uncertainty
- The Tesla owner’s manual confirms that Tesla vehicles surface software release notes on the touchscreen, but the Grok-specific claim in the provided evidence comes from a release-notes statistics page rather than a Tesla release note quoted directly here. [
5][
6]
- A Facebook snippet in the provided evidence claims a future “Hey Grok” wake word in Tesla version 2026.14, but that is not a strong source for this fact-check and should be treated as unverified here. [

Verdict
- Supported: xAI has speech APIs, and Tesla infotainment appears to have a Grok experience with selectable voices and voice-button launch. [

- Not supported: that “Grok 4.3” specifically acts as a real voice assistant across Grok Voice, Tesla infotainment, and support surfaces. [
