Directions : Read the following passage and answer the questions.
Voice or speaker recognition refers to a machine or program's ability to interpret dictation or understand and execute spoken commands. This technology has become increasingly prominent with the _____________ of artificial intelligence (AI) and intelligent assistants like Amazon's Alexa and Apple's Siri. Offering hands free interactions, voice recognition systems enable users to make requests, set reminders, and perform various tasks simply by speaking.
The process involves automatic speech recognition (ASR) programs that can identify and differentiate voices. Some ASR programs necessitate users to train the system for improved accuracy in converting speech to text. Evaluation of a voice's frequency, accent, and speech flow is integral to voice recognition systems.
While voice recognition and speech recognition are often used interchangeably, they have distinct meanings. Voice recognition identifies the speaker, whereas speech recognition assesses the content of what is said.
In practice, voice recognition software on computers converts analog audio into digital signals through analog-to-digital (A/D) conversion. This digital database of words or syllables is then compared to signals during pattern recognition. The size of the program's effective vocabulary depends on the computer's RAM capacity, with faster processing speeds enhancing search capabilities.
Voice recognition involves analyzing speech through models like the hidden Markov model or recurrent neural networks. The former breaks down spoken words into phonemes, while the latter uses previous outputs to influence current inputs, improving capabilities and accuracy with increased data.
The integration of voice recognition into smartphones and home devices like Google Home and Amazon Echo has made this technology ubiquitous. As more users engage with voice recognition, the wealth of data generated enhances the capabilities and accuracy of these systems, indicating a promising trajectory for the technology's future.
Why does the passage suggest that the wealth of data is a crucial factor in determining the positive course of development for voice recognition technology?
- A.
The substantial amount of data will allow users to obtain authentic results of their search requests.
- B.
It will provide a diverse and extensive range of speech patterns, accents, and variations, enriching the system's database.
- C.
More users will be engaged to contribute to the wealth of data
- D.
It enhances the capabilities of voice recognition systems to accurately interpret and respond to a wide array of voices and linguistic nuances
- E.
Both (b) and (d)
Show answer & explanation
Correct answer: E
Concept
In a Reading-Comprehension inference question you do not pick the option that merely sounds impressive; you pick the statement(s) that the passage's own wording supports. When an answer choice reads “Both X and Y”, it is correct only when EACH referenced statement is independently grounded in the text, so every referenced statement must be tested against the passage line by line.
Application
The closing line of the passage is the anchor: “As more users engage with voice recognition, the wealth of data generated enhances the capabilities and accuracy of these systems.” Two distinct ideas follow from it:
The diverse-database idea — more users means a wider spread of speech patterns, accents and variations feeding the system, which enriches its database. This matches the statement that the data “will provide a diverse and extensive range of speech patterns, accents, and variations, enriching the system's database.”
The improved-capability idea — a richer database lets the system interpret and respond accurately to many kinds of voices and linguistic nuances. This matches the statement that the data “enhances the capabilities of voice recognition systems to accurately interpret and respond to a wide array of voices and linguistic nuances,” and the passage backs it twice: in the closing line and in the earlier note that recurrent neural networks keep “improving capabilities and accuracy with increased data.”
Because both of these statements are independently supported by the passage, the choice that combines them is the one the passage suggests.
Cross-check
The statement about users obtaining “authentic results of their search requests” introduces a search-result outcome the passage never makes — the passage links data to system capability and accuracy, not to the authenticity of a user's search. The statement that “more users will be engaged to contribute to the wealth of data” restates the cause already given in the question rather than answering why the data matters for the technology's positive trajectory. Only the diverse-database statement and the improved-capability statement together capture the passage's reasoning.
