In some cases, a handheld electronic device may operate in a voice input mode or a scanner input mode. When operating in the voice input mode, the handheld electronic device may record and store audio data in memory. In some cases, the stored audio data may be communicated from the handheld electronic device (e.g., via a Wi-Fi connection) to one or more remote computing devices (e.g., for speech processing). When operating in the scanner input mode, the handheld electronic device may record and store item identifier information (e.g., as barcode data) in the memory. In some cases, the stored item identifier data may be communicated to the one or more remote computing devices (e.g., for item identification processing).
