Towards task-independent speech recognition
نویسندگان
چکیده
Despite the considerable progress made in the last decade, speech recognition is far from a solved problem. For instance, porting a recognition system to a new task (or language) still requires substantial investment of time and money, as well as expertise in speech recognition. This paper takes a first step at evaluating to what extent a generic state-of-the-art speech recognizer can reduce the manual effort required for system development. We demonstrate the genericity of wide domain models, such as broadcast news acoustic and language models, and techniques to achieve a higher degree of genericity, such as transparent methods to adapt such models to a specific task. This work targets three tasks using commonly available corpora: small vocabulary recognition (TI-digits), text dictation (WSJ), and goal-oriented spoken dialog

Speech Emotion Recognition Based on Power Normalized Cepstral Coefficients in Noisy Conditions
Automatic recognition of speech emotional states in noisy conditions has become an important research topic in the emotional speech recognition area, in recent years. This paper considers the recognition of emotional states via speech in real environments. For this task, we employ the power normalized cepstral coefficients (PNCC) in a speech emotion recognition system. We investigate its perfor...

In order to facilitate the entry of data into the computer and its digitalization, automatic recognition of printed texts and manuscripts is one of the considerable aid to many applications. Research on automatic document recognition started decades ago with the recognition of isolated digits and letters, and today, due to advancements in machine learning methods, efforts are being made to iden...
متن کاملExperiments on Speaker-independent V Using In-vehicle Hands
For speaker-independent voice command recognition, the acoustic models can be trained using either task-independent speech corpora or task-specific speech corpora. The first alternative could reuse available speech databases, without collecting task-specific speech data. On the other hand, it is expected to give lower recognition performance due to acoustic and vocabulary mismatches between the...
