Two common services provided are Text-to-Speech and Speech-to-Text. Typical capabilities for Text-to-Speech services include natural sounding voices, pitch tuning, speed control, and support for multiple languages. Speech-to-Text capabilities include easy-to-read, multiple language support, custom vocabulary, and ability to recognize multiple speakers.

Other common services are language translators, text analyzers, and conversation bot builders. The language translation services are used for secure, batch and real-time translations. Common capabilities for text analysis services are keyphrase extraction, sentiment analysis, entity recognition, language detection, and support for multiple languages. Conversation bots are conversational interfaces, also known as “chatbots.” We have seen significant growth in interest in chatbots over recent months.

IBM, Microsoft, and Salesforce offer linguistic analysis services. Linguistic analysis includes simplifying complex language concepts, parsing text, sentence separation and tokenization, part-of-speech tagging, and constituency parsing. IBM also offers a language classifier for classifying text passages, evaluating results, and building conversational applications.

Microsoft and SAP both offer spell check services, which not only help correct spelling errors but also help recognize brand names and slang, as well as understand homophones. Microsoft also offers a web language model, for automating tasks, joint and conditional probabilities, and next word completions.
