**Introduction** BOLT CTS CALLFRIEND CALLHOME Egyptian Arabic Transcripts and Translations, Linguistic Data Consortium (LDC) Catalog Number LDC2025T14, was developed by LDC and consists of transcripts and their corresponding English translations for 116 hours of conversational telephone speech between native speakers of the Arabic dialect spoken in Egypt. The DARPA BOLT (Broad Operational Language Translation) program developed machine translation and information retrieval for less formal genres, focusing particularly on user-generated content. LDC supported the BOLT program by collecting informal data sources -- discussion forums, conversational telephone speech, text messaging and chat -- in Chinese, Egyptian Arabic and English. The telephone data was transcribed, translated and annotated for various tasks including word alignment, treebanking, and co-reference. **Data** The source audio recordings consist of 274 telephone conversations taken from LDC's multilingual CALLFRIEND and CALLHOME series developed to support speech identification and language identification technology development. Transcribers were required to produce a verbatim transcript of all speech within a file using the CODA orthographic approach; diacritics are not included. Some transcripts include redactions for potential personally identifying information. Further information about the transcription methodology is contained in the transcription guidelines accompanying this release. All speech data was transcribed. The goal of the BOLT translation task was to translate the Arabic transcripts into fluent English while preserving the meaning present in the original Arabic text. Transcripts in the development and evaluation partitions received first pass and gold standard translations. Further information about the translation methodology is contained in the translation guidelines accompanying this release. 99% of the transcripts were translated into English. **Acknowledgement** This material is based upon work supported by the Defense Advanced Research Projects Agency (DARPA) under Contract No. HR0011-11-C-0145.
