Talk2Me: Automated linguistic data collection for personal assessment

Language is one the earliest capacities affected by cognitive change. To monitor that change longitudinally, we have developed a web portal for remote linguistic data acquisition, called Talk2Me, consisting of a variety of tasks. In order to facilitate research in different aspects of language, we provide baselines including the relations between different scoring functions within and across tasks. These data can be used to augment studies that require a normative model; for example, we provide baseline classification results in identifying dementia. These data are released publicly along with a comprehensive open-source package for extracting approximately two thousand lexico-syntactic, acoustic, and semantic features. This package can be applied arbitrarily to studies that include linguistic data. To our knowledge, this is the most comprehensive publicly available software for extracting linguistic features. The software includes scoring functions for different tasks.

语言能力是人类认知变化最早受到影响的能力之一。为了纵向监测这种变化，我们开发了一个名为 Talk2Me 的远程语言数据采集网络平台，该平台包含多种任务。为了促进语言不同方面的研究，我们提供了包括任务内和任务间不同评分函数之间关系的基线。这些数据可用于增强需要规范模型的研究；例如，我们提供了识别痴呆症的分类基线结果。这些数据与一个全面的开源软件包一同公开发布，该软件包能够提取大约两千个词汇-句法、声学和语义特征。该软件包可任意应用于包含语言数据的各项研究中。据我们所知，这是目前公开可用的最全面的提取语言特征的软件。该软件包括针对不同任务的评分函数。
