NLP & Speech Technology


Enhance your Natural Language Processing and machine learning solutions with our top-grade training data



Natural Language Processing (NLP) technology is rapidly evolving due to an increased interest in human-to-machine communications. NLP makes it possible for computers to read text, understand speech, interpret it, summarize it and measure sentiment. NLP is the driving force behind many AI solutions, but it requires a lot of adeptly handled, labeled and organized training data. The more data you use to train your model, the better it gets.

At Appen, we're proud of our strong linguistic background. We have global crowd who work in over 170 countries and have expertise in over 235 languages. We've helped countless companies across industries like retail/e-commerce, finance, insurance, medical, transportation and more achieve their NLP project goals.

We provide the training data to help build intelligent systems capable of understanding and extracting meaning from human text and speech for a diverse range of use cases, such as chatbots, voice assistants, search relevance, sentiment analysis and more.

Text Collection



To build world class language-based machine learning applications interpreting textual data from a variety of sources, we offer multilingual Text Data Collection Services in all major languages and dialects. With our Text Utterance Collection services, gather large volumes of high-quality, customized text utterances for training chatbots and other conversational AI models. Use our Text Generation services to generate scenario-based responses or conversations amongst native speakers with optional subsequent Semantic Annotation to create a text corpus for chatbot training or Natural Language Processing.

Annotation Capabilities



With a large range of data annotation capabilities built to serve many different industries, we are well-placed to serve a variety of project types.

Many of our annotation capabilities have Smart Labeling features which use machine learning assistance in the data annotation process to automate and improve productivity, quality, and delivery of your data collection and data annotation projects.



Text



Text Annotation (NER, POS)


Expand on your NLP labeling by connecting named entities or parts of speech within relationships.


Text Classification (Sentiment, Intent, Content)


Increase chances of having a meaningful conversation by understanding intents behind customer queries and get insights from customer interactions.


Entity Extraction


Highlight and categorize relevant entities and train your model to derive key information from big volumes of text to improve the cognitive ability of your model.


Search Result Evaluation


Rank search results and improve user experience by using this data to train models to return the most relevant search results for the customer's query.


Text Evaluation and Post-Editing


Evaluate the naturalness and relevance of the text generated by NLP models, such as machine translation models and other sequence models with the help of our multi-lingual specialists.



Audio



Audio Annotation


Segment audio into layers, speakers and timestamps for your Audio Speech Recognition and other audio models. 


Audio Transcription


Transcribe spoken audio into text or validate machine-generated transcriptions. Leverage built-in NLP models to improve transcription quality and efficiency.


Audio Classification


Use sound categorization or Utterance classification to classify audio based on language, dialect, semantics, and other features.
