American English Spoken Lexicon

Introduction This lexicon contains pronunciations captured in individual audio files for 53,602 of the most common words in English. Data 50,892 words were chosen from LDC's CALLHOME American English Lexicon on the basis of their frequency in the data that were used in creating the 1994 CSR Language Model Text Corpus ("CSR-III Text Corpus," LDC95T6). The sources for the language model include Wall Street Journal (1987-1994), Associated Press (1989-1991), and San Jose Mercury News (1991); all taken from the three CD-ROM volumes of TIPSTER (LDC93T3A). To extend the coverage of common words that happen not to occur in the LDC corpora sampled, an additional 2,922 words (ie. compounds, companies, places, languages, and numerals) were added from other sources. Each word was read by the speaker in a quiet recording studio, using a Sennheiser HMD 410 microphone and a Sony DAT recorder. The recordings were downsampled to 16KHz for storage on disk with the individual lexical utterances segmented into separate waveform files, with a consistent margin of silence on both sides of each word. The CD-ROMs were created using the ISO-9660 Level 2 data format, along with Rock Ridge extensions. All common computer operating systems should be able to read the full-length file names. The corpus has since been converted to a web downloaded file. Updates There are no updates at this time.

引言 本词典收录了英语53602个最常用单词的单条音频录制发音。
数据 50892个单词选自语言数据联盟（Linguistic Data Consortium, LDC）的CALLHOME美式英语词典，选取依据为其在构建1994年语音识别语言模型文本语料库（"CSR-III文本语料库"，LDC95T6）所用数据中的出现频率。该语言模型的数据源包括《华尔街日报》（1987-1994年）、美联社（1989-1991年）以及《圣何塞信使报》（1991年），所有数据均取自TIPSTER项目的三张CD-ROM光盘（LDC93T3A）。为覆盖未在上述LDC语料库中出现的常用单词，又从其他来源新增了2922个单词（包括复合词、企业名称、地名、语言名称及数字）。所有单词均由发音人在安静的录音棚内录制，使用森海塞尔（Sennheiser）HMD 410麦克风与索尼（Sony）DAT录音机。录制的音频被下采样至16kHz以存储至磁盘，同时将每条词汇发音分割为独立的波形文件，每个单词的前后均保留一致长度的静音余量。该数据集的CD-ROM采用ISO-9660 Level 2数据格式，并附带Rock Ridge扩展协议，所有主流计算机操作系统均可读取完整长度的文件名。该语料库现已转换为可网络下载的文件格式。
