The work reported in this article developed a home automated system using voice activation. This is with a view to providing users complete control over electrical appliances using simple easy to remember voice commands on an Android mobile device. This work was implemented using the Atmega 328 microcontroller, Relays and a Wi-Fi shield. The human voice is first converted to text using a Natural language processing tool from the Android based application. Thereafter, the text is sent over the internet via the PubNub to the microcontroller. The Atmega 328 microcontroller was programmed on an Arduino using C programming language and the Android based application was developed using Android Software Development Kit. Results obtained from the testing show that the implemented system achieves the mean scores of 8, 7.6, and 7.2 for ease of use, learnability and effectiveness respectively justifying the fact that the system is capable of controlling appliances by changing their state (ON/OFF) from remote a location with a response time within the reasonable limit.

The unprecedented success of speech recognition methods has stimulated the wide usage of intelligent audio systems, which provides new attack opportunities for stealing the user privacy through eavesdropping on the loudspeakers. Effective eavesdropping methods employ a high-speed camera, relying on LOS to measure object vibrations, or utilize WiFi MIMO antenna array, requiring to eavesdrop in quiet environments. In this paper, we explore the possibility of eavesdropping on the loudspeaker based on COTS RFID tags, which are prevalently deployed in many corners of our daily lives. We propose Tag-Bug that focuses on the human voice with complex frequency bands and performs the thru-the-wall eavesdropping on the loudspeaker by capturing sub-mm level vibration. Tag-Bug extracts sound characteristics through two means: (1) Vibration effect, where a tag directly vibrates caused by sounds; (2) Reflection effect, where a tag does not vibrate but senses the reflection signals from nearby vibrating objects. To amplify the influence of vibration signals, we design a new signal feature referred as Modulated Signal Difference (MSD) to reconstruct the sound from RF-signals. To improve the quality of the reconstructed sound for human voice recognition, we apply a Conditional Generative Adversarial Network (CGAN) to recover the full-frequency band from the partial-frequency band of the reconstructed sound. Extensive experiments on the USRP platform show that Tag-Bug can successfully capture the monotone sound when the loudness is larger than 60dB. Tag-Bug can efficiently recognize the numbers of human voice with 95.3%, 85.3% and 87.5% precision in the free-space eavesdropping, thru-the-brick-wall eavesdropping and thru-the-insulating-glass eavesdropping, respectively. Tag-Bug can also accurately recognize the letters with 87% precision in the free-space eavesdropping.

A popular idea in Computer Assisted Language Learning (CALL) is to use multimodal annotated texts, with annotations typically including embedded audio and translations, to support L2 learning through reading. An important question is how to create the audio, which can be done either through human recording or by a Text-To-Speech (TTS) synthesis engine. We may reasonably expect TTS to be quicker and easier, but humans to be of higher quality. Here, we report a study using the open-source LARA platform and ten languages. Samples of LARA audio totaling about three and a half minutes were provided for each language in both human and TTS form; subjects used a web form to compare different versions of the same item and rate the voices as a whole. Although human voice was more often preferred, TTS achieved higher ratings in some languages and was close in others.

<p>This thesis takes the critical response generated by Kazuo Ishiguro’s The Buried Giant, his most recent novel, as an invitation to re-examine the overall literary ‘experiment’ of his body of work. Ishiguro’s novels, regardless of their genre, message, or cultural moment, create experiences in which the reader engages with each narrator as if they were a human being. His attention to stylistic and formal detail foregrounds our awareness of his art in each text, and much scholarship focuses on overarching discussions of memory, identity, and history; however, this all relies upon the empathy that the texts generate between the character-narrator and the reader. The commitment to mimesis over the synthetic or thematic dimensions of the text, to draw on the theoretical model of character presented by James Phelan, often remains covert throughout each novel, but character mimesis nevertheless acts as both an accessible entry point to the novels, and a consistent touchstone throughout and across the texts.  Upon the publication of The Buried Giant, Ishiguro was met with criticism and dissatisfaction from numerous reviewers and scholars, despite general public appreciation of the novel. At the heart of this dissatisfaction lies a sense that Ishiguro’s foray into fantasy lacks the affective power of his iconic artlessness. Specifically, The Buried Giant appears to lack a central, consistent, human voice to hold together the synthetic and thematic work that the text performs.  This thesis presents an argument that finds within The Buried Giant the presence of a first-person voice that, rather than diverging from each of Ishiguro’s previous narrators, takes his experimentation with the first-person voice to a new extreme. This reading allows me to locate The Buried Giant more squarely back in conversation with the rest of Ishiguro’s oeuvre, by identifying a covert but vital thread that exists beneath the shifts in genre, thematic and synthetic choices, and context of the novel. I explore the establishment of character mimesis across Ishiguro’s body of work, how this feeds into both the dissatisfaction with The Buried Giant and my reconciliation of the novel to his earlier works, and finally how The Buried Giant and its shift to both a covert narrative voice and the genre of fantasy provides an opportunity to re-examine Ishiguro’s use of non-mimetic structures and generic conventions in his first six novels around the central, mimetic narrator.  As suggested, this approach draws significantly on the theory of character presented by James Phelan, which allows for comprehensive consideration of diverse textual functions that occur both throughout a given text and across several texts of widely varying genres and perspectives. I touch on notions of unreliability, memory and subjective history, trauma, and identity performance, each of which are central to many pieces of scholarship on Ishiguro’s novels; however, the aim of this project is to swiftly push beyond readings that prioritise synthetic and thematic dimensions of the novels to reach the heart of how the voices who capture their own stories completely entrance Ishiguro’s readership.</p>
