Toshiba M550 Series (hands-free Alexa)

This model has a built-in far-field microphone, which is the hardware hands-free voice control uses.

Amazon's Fire TV device specifications for the "Toshiba M550 Series 4K UHD Smart Fire TV, Released 2021" (55, 65 and 75 inches) say the TV "supports a hands-free Alexa experience with a built-in mic-array", and list far-field (hands-free) Alexa control as "Supported". For most other Toshiba Fire TVs the same page says hands-free control works only through a linked Echo device, so this model is different.

Firmware support status hasn't been confirmed for this model from a citable source yet.

What that actually means for your TV →

No dated Toshiba or Amazon firmware record or minimum software-support term for this specific model could be found, unlike Samsung's public seven-year Tizen commitment. Stays unverified rather than assumed either way.

This model has Toshiba's ACR feature (branded "Automatic Content Recognition"), which analyses on-screen content — including over HDMI — to identify what's playing.

What ACR is and how to turn it off →

This model runs Fire TV, and Amazon's own official Automatic Content Recognition help page — not Toshiba's — describes the feature directly: when enabled, it fingerprints content "through connected devices, such as a cable set-top-box" (not just Amazon's own apps) by sampling audio or pixels and matching against a database, and can be managed at Settings → Preferences → Privacy Settings → Automatic Content Recognition. Amazon's page doesn't state whether it's on by default. Enabling it on one Fire TV device doesn't enable it on others.
