Smart TV voice control and remote features transform how users interact with their televisions, offering hands-free convenience and accessibility. Modern smart TVs from brands like Samsung, LG, and TCL integrate virtual assistants such as Bixby, Alexa, and Google Assistant, allowing voice commands for channel navigation, app launches, and smart home device control. The setup process typically involves enabling voice recognition through TV settings, linking accounts (e.g., Amazon or Google), and adjusting preferences for wake-up phrases and command sensitivity. Remote controls now feature dedicated microphone buttons, directional pads for menu navigation, and shortcuts to streaming services, though newer models like Samsung’s solar-powered remote omit traditional keypads for a streamlined design.

Key findings from the search results include:

• Voice assistant compatibility: Samsung TVs support Bixby and Alexa (Google Assistant discontinued March 2024), while LG TVs use built-in AI services requiring WebOS settings configuration ^[1][6].
• Setup steps: Voice control activation involves navigating to Settings > General > Voice (Samsung) or Settings > AI Service > Voice Recognition (LG), followed by account linking and permission adjustments ^[1][6].
• Remote functionality: Modern remotes combine voice buttons, directional pads, and app shortcuts, with some models (e.g., Samsung S90C) using solar charging and USB-C backup power ^[3][5].
• Accessibility focus: Voice control benefits users with mobility challenges, enabling full TV operation (channel changes, content searches) without physical remotes, though setup may require additional devices like Chromecast for seamless integration ^[4][8].

Setting Up and Using Smart TV Voice Control

Configuring Voice Assistants on Samsung and LG TVs

Voice control setup varies by brand but follows a consistent pattern of enabling the feature in system settings and linking external accounts. Samsung TVs prioritize Bixby and Alexa, while LG relies on its proprietary AI service. The process requires an active internet connection and, in some cases, additional hardware for older models.

For Samsung TVs, the setup begins in the Settings menu:

• Navigate to Settings > General > Voice and select either Bixby or Alexa ^[1].
• Bixby: Adjust voice wake-up settings (e.g., "Hi, Bixby") and language preferences. Bixby supports multiple languages but requires a Samsung account for full functionality.
• Alexa: Scan a QR code displayed on-screen to link an Amazon account. This enables skills like smart home device control and third-party app integration.
• Google Assistant is no longer supported as of March 1, 2024, though existing setups may retain limited functionality ^[1].
• Voice command examples: Users can say, "Open Netflix", "Volume up", or "Search for action movies" after pressing the remote’s microphone button ^[8].

LG TVs use a slightly different approach:

• Access Settings > General > AI Service > Voice Recognition Settings and enable the feature ^[6].
• Ensure Direct Voice Recognition is turned on to allow hands-free commands like "Turn on the TV" when the device is in standby mode.
• WebOS requirements: TVs must run WebOS 3.0 or later, with Always Ready and Quick Start+ enabled for voice wake-up functionality ^[6].
• Language support: LG’s voice recognition supports English, Spanish, and French, with regional variations available in settings.

Accessibility considerations play a critical role in voice control adoption. Users with limited mobility, such as those with multiple sclerosis, may require full voice integration for tasks like channel surfing or app navigation. Google Assistant, when paired with a Chromecast with Google TV, can bridge gaps for TVs with basic voice support, offering commands like "Play Stranger Things on Netflix" or "Switch to HDMI 2" ^[4]. For older TVs without built-in voice features, IR-based solutions (e.g., SwitchBot hub) can mimic remote signals via voice assistants like Alexa or Siri ^[7].

Navigating Smart TVs with Remote Controls

Modern smart TV remotes blend traditional buttons with voice activation and touch-sensitive controls, though designs vary significantly by manufacturer. Samsung’s Smart Remote, introduced with models like the S90C, exemplifies this shift by eliminating number keypads in favor of a minimalist layout with solar charging capabilities.

Key remote features and functions:

• Microphone button: Press and hold to activate voice assistants (e.g., Bixby or Alexa). On Samsung remotes, this button is centrally located above the directional pad ^[3][5].
• Directional pad: Used for menu navigation, with the center button confirming selections. Long-pressing up on some remotes also triggers voice commands ^[3].
• Dedicated app buttons: Shortcuts for Netflix, Disney+, and Prime Video are pre-programmed, reducing the need to navigate through menus ^[5].
• Volume and channel controls: Traditional rocker buttons adjust audio levels and cycle through channels, though some models (e.g., LG Magic Remote) include point-and-click functionality for on-screen cursors ^[8].
• Smart Hub/Quick Settings: The Smart Hub button (Samsung) or Home button (LG) opens the main interface for apps, inputs, and settings. Quick Settings provide instant access to display modes, sound profiles, and network options ^[3].

Advanced remote setups cater to users seeking to upgrade older TVs:

• Hidden service menus: Some Samsung 7-series TVs can unlock voice control and Bluetooth by entering a button sequence (e.g., Mute > 1 > 8 > 2 > Power) to access a service menu. This allows pairing with newer smart remotes, though incorrect settings may void warranties ^[9].
• Universal remotes: Devices like the SwitchBot Hub use IR blasters to replicate traditional remote signals, enabling voice control via Alexa or Google Assistant for non-smart TVs ^[7].
• Solar-powered remotes: Samsung’s eco-friendly remote charges via indoor lighting or USB-C, eliminating battery replacements. The remote’s slim design includes only essential buttons, relying on voice commands for complex tasks ^[5].

Troubleshooting common issues:

• Voice commands not recognized: Ensure the TV’s microphone is unobstructed and the remote is within range (typically 3–5 meters). For LG TVs, verify Quick Start+ is enabled in Settings > General > Additional Settings ^[6].
• Remote unresponsive: Replace or recharge batteries (if applicable) or reset the remote by removing batteries for 30 seconds. For solar remotes, expose to light for 1–2 hours ^[5].
• App shortcuts not working: Update the TV’s firmware via Settings > Support > Software Update and re-link streaming accounts ^[3].
