When Google launched the Pixel 6 in 2021, it introduced a host of new features powered by its first in-house chip, the Tensor. Among these innovations were several AI-powered call tools that revolutionized the smartphone calling experience. Fast forward to 2023, and the Pixel 8 has arrived with the upgraded Tensor G3 chip and an impressive set of refinements. The evolution of AI call features between these two models showcases Google's commitment to making communication smarter, smoother, and more accessible.
The Foundation: Google Tensor and the Rise of AI Calling Features
The Tensor chip was Google's bold departure from Qualcomm processors. This custom silicon was specifically designed to support advanced machine learning and artificial intelligence functions directly on the device. In the Pixel 6, this power translated into pioneering call features such as:
- Hold for Me: Google Assistant waits on the line during hold music and alerts the user when a representative comes on.
- Call Screen: Automatically screens calls from unknown numbers, allowing users to read a transcript of why the caller is dialing in real-time.
- Direct My Call: Offers on-screen menus for navigating when calling toll-free numbers.
These features made the Pixel 6 a milestone in AI-assisted calling. But while its capabilities were groundbreaking for the time, the Pixel 8 has taken these tools to new levels of polish and intelligence.
Pixel 6 vs. Pixel 8: What’s Evolved?
At first glance, the list of AI calling features doesn’t seem all that different on the Pixel 8. However, it’s in the refinements, usability, and processing power where the Pixel 8 truly shines. Let’s break down the core upgrades:
1. Call Screen – Faster and Smarter
On the Pixel 6, Call Screen was a revelation. But it wasn’t perfect—there could be delays in transcription, and the Assistant occasionally misunderstood the caller. The Pixel 8 improves this feature with:
- Enhanced AI Accuracy: The updated Tensor G3 chip processes speech more fluidly, leading to better transcription accuracy and understanding of caller intent.
- More Natural Assistant Voice: The Pixel 8’s Assistant sounds more lifelike, creating a smoother interaction that feels less robotic.
Not only is it easier to understand unknown callers, but the assistant can now handle more nuanced replies, reducing your chances of picking up a telemarketing or scam call.
2. Direct My Call – Now With Visual Improvements
“Direct My Call” was another innovative feature in the Pixel 6, especially useful for navigating automated phone systems. Now, in the Pixel 8, it comes with visual and speed improvements:
- Quicker Menu Generation: Menus are detected and displayed faster, thanks to improved machine learning models.
- Ghost Menus in More Places: Initially limited to toll-free numbers in the U.S., the Pixel 8 now supports this feature on a broader range of services and even with inconsistent menu formats.
The AI also accounts for overlapping prompts, a weak spot in earlier versions. This means less confusion when multiple options are spoken quickly one after the other.
3. Hold For Me – Subtle Touches, Major Difference
Originally released with the Pixel 5 and refined in Pixel 6, “Hold For Me” uses Google Assistant to stay on the line during long hold times. While functional in the Pixel 6, there were occasional lags in detection or delays in alerts. The Pixel 8 optimizes this well-loved feature by:
- Reducing Assistant Lag: Thanks to the Tensor G3’s better performance, it takes less time for the Assistant to notify when a representative answers.
- Speech Context Awareness: It’s now better at identifying when a human finally joins the call, especially in noisy audio environments.
This means users can rely more confidently on the Assistant without constantly checking in on the call.
Exclusive Pixel 8 Features
While many AI call features appear on both the Pixel 6 and Pixel 8, the newer device introduces exclusive tools and updates backed by stronger AI capabilities:
Clear Calling – Built for Disruptive Environments
A Pixel 8 exclusive, Clear Calling enhances the audio quality of who you’re talking to by filtering out background sounds. Unlike other noise suppression technologies that operate only on your end, this feature improves the caller’s audio before it reaches your ear.
Some of its key advantages include:
- Improved Speech Recognition even in crowded environments like train stations or cafes.
- Automatic Noise Detection that adjusts in real-time to changing audio conditions.
This makes conversations clearer and less frustrating—especially for those who frequently take calls in noisy places.
Summarize Voicemails – A Productivity Boost
Another Pixel 8-exclusive perk is the smart voicemail transcription and summary feature. Rather than listen through every message, users receive an AI-generated summary that highlights the core intent of the message.
This feature is ideal for:
- Busy professionals who receive dozens of voicemails weekly.
- Situations where listening to audio isn't practical (e.g. commuting or in a quiet room).
AI at Your Fingertips: The Role of Tensor G3
Much of the evolution from Pixel 6 to Pixel 8 in AI call features boils down to Google’s powerful new chip. The Tensor G3 provides:
- More neural cores dedicated to improving machine learning directly on the device.
- Energy-efficient processing for longer battery life during Assistant-led tasks.
- Smoother execution of simultaneous tasks, like screening a call while recording audio or using another app.
While the Tensor G1 in the Pixel 6 started this journey, it’s clear that the newer chip significantly lifts limitations and unlocks more enhanced, real-time call features.
Final Thoughts: Should You Upgrade?
The Pixel 6 is still a solid phone, especially given it was Google's AI breakthrough device. But if phone call AI features are a key part of how you use your smartphone, the Pixel 8 offers a substantially enhanced experience:
- Faster and more accurate live call handling.
- Features like Clear Calling and voicemail summaries that make communication more efficient.
- Smarter, more natural interactions that feel less like tech and more like an assistant.
In a world still full of phone trees, robocalls, and voicemail spam, the Pixel 8 stands out as one of the smartest companions for staying connected. Whether you take calls for work, family, or managing life logistics, you’ll appreciate just how far AI has come in just two phone generations.
