How Do Voice Input Key Switches Work?
Voice input key switches work by converting speech into actions on a connected device. They contain a microphone to capture the user’s voice, speech recognition software to interpret the audio input, and an output mechanism to execute commands on the paired device.
The main components of a voice input key switch are:
- Microphone – Detects and captures the user’s speech
- Speech recognition software – Analyzes the audio input and converts it to text commands
- Output device – Sends the command text to the connected device to perform actions
The microphone picks up the user’s voice and converts it to an audio signal. The speech recognition software analyzes this signal, matches it against known speech patterns, and converts it to text.
This text command is then sent to the connected device via the output mechanism, which could be Bluetooth, USB, or another wireless protocol. The device receives the text command and executes the associated action, such as opening an app, typing text, or navigating a menu.
Voice input key switches allow for completely hands-free operation of phones, tablets, computers, and other devices. This makes them very useful for people with limited mobility.
Where Are Voice Input Key Switches Located?
Voice input key switches are typically mounted near the user on their wheelchair or bed to make them easily accessible. They need to be positioned in a spot that allows for optimal microphone pickup of the user’s voice commands. Many voice input key switches are connected to the user’s device via a cable, but wireless options are also available that use Bluetooth to connect.
For wheelchair users, voice input key switches are often mounted to one of the arms of the chair within easy reach of the user’s hand. A flexible gooseneck allows positioning of the microphone in the optimal spot to pick up the user’s voice, usually about 6 inches from their mouth. The key switch is connected to a small control box that can be mounted underneath the chair.
For bedridden users, the voice input switch may be attached to a flexible stand that can be positioned near their head. Again a flexible microphone gooseneck allows optimal positioning to pick up voice commands. In some cases a lap tray is used with the switch mounted to it.
With wireless voice input switches, the microphone and key switch are built into a small independent unit. This gives more flexibility for mounting positions around the user. The wireless connection to the user’s computer or device eliminates the need for cables.
Key Features of Voice Input Key Switches
Voice input key switches have several key features that impact their usability and functionality:
Microphone Sensitivity/Range – Voice input switches utilize built-in microphones to detect voice inputs. The microphone sensitivity determines the range at which voice commands can be detected. More advanced switches have multi-array microphones with noise cancellation for picking up voice commands accurately.
Supported Voice Commands – Basic voice input switches allow for dictating text. More advanced options support voice commands to open apps, navigate screens, and control phone functions through AI assistants like Google Assistant or Bixby.
Wireless Connectivity – Some switches utilize Bluetooth to connect wirelessly to mobile devices. This allows for more flexible positioning. Switches without wireless rely on the audio jack for a physical connection.
Battery Life – Switches with wireless connectivity have built-in rechargeable batteries. Battery life varies from 8-12 hours of continuous use before needing to recharge. Switches without wireless connectivity do not require batteries.
Configuring a Voice Input Key Switch
Properly configuring a voice input key switch is important for getting the most out of this assistive technology. There are a few key steps involved in setting up and customizing a voice input switch to meet a user’s needs:
