# Spontaneous activities While users are often able to recite sentences presented in a read-aloud activity, they continue to lag in having real-life conversations. This is because readable prompts provide visual cues on how to produce sounds but they limit the user from producing original responses. Therefore merely measuring oral skills based on read-aloud scripted activities is not sufficient. To truly measure a user's spoken language abilities, we need to prompt the user in to producing an original or spontaneous response to open-ended questions. To this effect, the Speechace API provides the following capabilities:\ \ **a.** [**Open-ended scoring**](/features/spontaneous-activities/open-ended-scoring.md)**:** This capability evaluates a user's free speech spontaneous response up to 2 minutes in length and provides a **pronunciation**, **fluency**, **vocabulary**, **grammar** and **coherence** score along with a **transcript** of the candidate's response. **b.** [**Task achievement scoring**](/features/spontaneous-activities/task-achievement-scoring.md)**:** In addition to scores provided by open-ended scoring, Task achievement scoring provides a fine grained measure of the comprehensiveness and completeness of the user's response for a given task. \ \ In the next few sections, we will discuss these capabilities in more detail. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://api-docs.speechace.com/features/spontaneous-activities.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
