Switchboard Telephone Speech Corpus is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Switchboard Telephone Speech Corpus rather than just read about it. In short: The Switchboard Telephone Speech Corpus is a corpus of spoken English language consisted of almost 260 hours of speech. It was created in 1990 by Texas Instruments via a DARPA grant, and released in 1992 by NIST.

Key takeaways

Switchboard Telephone Speech Corpus belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Switchboard Telephone Speech Corpus to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Switchboard Telephone Speech Corpus from memory before moving on to harder problems.

Reference excerpt

The Switchboard Telephone Speech Corpus is a corpus of spoken English language consisted of almost 260 hours of speech. It was created in 1990 by Texas Instruments via a DARPA grant, and released in 1992 by NIST. The corpus contains 2,400 telephone conversations among 543 US speakers (302 male, 241 female). Participants did not know each other, and conversations were held on topics from a predetermined list. Switchboard-2 Phase II was collected in 1999 and includes "4,472 five-minute telephone conversations involving 679 participants". The corpus was used for development of speech recognition algorithms.

Worked examples

Example 1 — a first encounter with Switchboard Telephone Speech Corpus

Start with the simplest possible case. Write down what Switchboard Telephone Speech Corpus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Switchboard Telephone Speech Corpus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Switchboard Telephone Speech Corpus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Switchboard Telephone Speech Corpus

In research: Switchboard Telephone Speech Corpus appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Switchboard Telephone Speech Corpus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Switchboard Telephone Speech Corpus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Applied linguistics, Corpus linguistics stubs, English corpora, so understanding it makes those chapters shorter.
In everyday life: Look for Switchboard Telephone Speech Corpus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
