Usability of input methods within mobile devices: A comparative study between Voice-to-text vs soft keyboard Rudraksh Gupta BCA, Department of Computer Science and Engineering, Guru Nanak Dev University, Amritsar ---------------------------------------------------------------------***---------------------------------------------------------------------

Abstract - This study, rooted in Human-Computer

the speed of voice-to-text and the precision of typing on a keyboard.

Interaction (HCI), meticulously compares mobile input methods— Voice-to-text and Soft Keyboard. The research was conducted by Guru Nanak Dev University student and scrutinizes their advantages and limitations through a 2 × 2 within-subjects design with 10 participants. Contrary to expectations within the HCI framework, Soft Keyboard consistently outperforms Voice-to-text in input speed, indoors and outdoors. This challenges assumptions and calls for future HCI research to embrace a comprehensive evaluation framework, considering factors like user preferences and accuracy, ensuring mobile interfaces align seamlessly with user needs.

This research seeks to explore HCI by analyzing the comparative advantages and disadvantages of two distinct input methods – voice-to-text and standard keyboard input. Through an in-depth investigation, this study aims to provide insights into the optimal input method for different scenarios, thus contributing to the design of user interfaces.

The research conducted by Carnegie Mellon, titled "A Comparison of Speech and Typed Input," (Hauptmann, 1990) provides a thorough exploration of the dynamics between voice and keyboard input within the context of digit entry tasks. The primary aim of the study is to conduct a detailed comparison between these two input modalities, shedding light on their respective advantages and limitations.

1.INTRODUCTION In our rapidly changing, technology-driven world, the devices we use daily have a large impact on how we interact with the digital world. Human-Computer Interaction (HCI) looks to study this essential connection while focusing on enhancing the user experience. Within HCI, the choice of input method is a crucial decision, greatly affecting how users engage with systems. This research delves into two distinct input methods: voice-totext and standard keyboard input, aiming to shed light on their relative advantages and disadvantages.

In terms of experimental setup, the research encompassed two experiments: one involving the presentation of digit strings on a screen and the other requiring subjects to read from a paper (Hauptmann, 1990). Three distinct data entry modes were considered—voice only, voice with keyboard correction, and keyboard only. Each experiment involved subjects entering three lists of 66-digit strings, facilitating a comprehensive examination of various input conditions (Hauptmann, 1990).

Recent years have seen impressive advancements in voice recognition technology. These improvements have created a new era where users can speak to their devices, reducing the need for typical keyboard input. The evolution of this technology is groundbreaking as it completely transforms the way we communicate with digital devices.

Crucially, the study's findings regarding input duration time highlight the efficiency of speech input. The average difference between pronouncing a digit string and typing one was reported to be less than 2 seconds in both experiments (Hauptmann, 2022). Real-time response and accurate speech recognition emerged as pivotal factors influencing speech as a preferable communication mode (Hauptmann, 1990).

The appeal of voice-to-text input lies in its speed and accessibility for users with impairments. Users can talk to their devices and see their words appear as text rather than typing each word out using their fingers. This technology has made voice-to-text input a very intriguing alternative to traditional keyboard input. However, beneath these advantages, voice-to-text input also produces its own set of challenges. Users often have concerns about its accuracy and overall usability. There are questions surrounding potential trade-offs between
