6 Minute English from bbclearningenglish.com Hello and welcome to 6 Minute English from BBC Learning English.
2
I'm Beth.
3
And I'm Neil.
4
Don't forget that you can find a transcript and a quiz for this episode on our website, bbclearningenglish.com.
5
Now, today, Neil, we're talking all about solving crime.
6
Do you think you'd be a good detective?
7
Actually, no, Beth, I think.
8
My brain's not very good with details.
9
Today, we'll be talking about how artificial intelligence might help detectives and the police investigate crimes.
10
But first, I have a question for you, Beth.
11
In the UK, lots of people enjoy watching fictional detectives on TV.
12
These programmes are called murder mysteries and tell the story of a detective solving a crime.
13
In 2020, a magazine called the Radio Times asked readers who their favourite TV detective was.
14
So who do you think was the most popular?
15
Was it A, Sherlock Holmes,
16
B, Hercule Poirot or C, Miss Marple?
17
Surely it's Sherlock Holmes.
18
Well, you sound very sure but I will reveal the answer at the end of the programme.
19
Now, when the police are investigating crimes in the real world,
20
their techniques are often quite different from what we see on television.
21
Yes, solving crimes involves collecting and reviewing lots of evidence,
22
like DNA, fingerprints or CCTV.
23
All of this work takes a lot of time.
24
So can AI help police speed up the work and even solve crimes?
25
That's the question listener Alistair had for the BBC Radio 4 programme The Artificial Human.
26
And host Alex Krotoski wanted to know more.
27
So Alistair, why are you asking this question?
28
Tell us a little bit about yourself and where you're coming from.
29
So, my name's Alistair and I'm a serving police officer.
30
My background is with investigation.
31
I'm looking at artificial intelligence and thinking,
32
what can it do for me?
33
Alex asks Alistair to explain where he's coming from.
34
This means explain his perspective or point of view.
35
In informal English, we'll often ask someone,
36
do you get where I'm coming from?
37
And we're asking whether they understand our opinion or perspective.
38
Alistair explains that he's interested in how artificial intelligence could help solve crimes
39
because he's a police officer with a background in investigations.
40
If you have a background in something,
41
it means most of your previous work or experience was related to something.
42
For example, I work as a producer at BBC Learning English now making programmes but my background is in classroom teaching.
43
Alistair talks about using artificial intelligence for training and asks,
44
what can it do for me?
45
This means, how can artificial intelligence help or improve something?
46
When a crime happens, police officers have to collect and review a lot of information to find evidence.
47
When you have a lot of information to review,
48
it can be difficult to know what's important and find patterns which might be relevant to the crime.
49
But Professor Ruth Morgan, an expert in crime and forensic science,
50
thinks AI could help speed up police work,
51
as she told BBC Radio 4's The Artificial Human.
52
I think we're seeing a renaissance in the pattern recognition forms of evidence,
53
so finger marks, footwear marks.
54
There's been lots of challenges with those forms of evidence over the last ten years,
55
probably, going a little bit out of favour.
56
And yet, what we're beginning to see now with AI is
57
that you can take a photo of a mark with your phone,
58
compare that mark to the database and get real-time insight.
59
Ruth says there's a renaissance in looking at patterns in evidence,
60
such as finger marks or footwear marks.
61
Renaissance means new interest or activity in a particular topic or area.
62
This kind of evidence went a little bit out of favour over recent years because of the excitement around DNA evidence.
63
If something is out of favour,
64
it's less popular or appealing.
65
But AI could mean that patterns in finger marks or footwear marks are useful in solving crimes again.
66
This is
67
because AI can be used to compare a picture of a mark with a database of pictures from other crimes
68
and get real-time insight.
69
The adjective real-time means the information is presented at the same time that it's happening.
70
Yes.
71
AI can compare lots of information very quickly,
72
which makes finding patterns in evidence much easier and more reliable.
73
There are some problems with using AI to solve crimes, though.
74
To find these patterns, lots of private information would need to be collected,
75
and police usually have to give clear reasons why they need access to certain information in their investigations.
76
It's unlikely an AI-powered robot would ever replace a detective any time soon.
77
Yes, and that reminds me of your question, Neil.
78
I said that Sherlock Holmes was maybe the most popular detective.
79
Was I right?
80
You were absolutely right.
81
And I think people should try the quiz on our website to find out how much they know as well.
82
It's at bbclearningenglish.com.
83
OK, let's recap the vocabulary we've learned,
84
starting with the expression where you're coming from,
85
which means your opinion or perspective on something.
86
Your background is the area that you have the most work experience in.
87
The question, what can this do for me,
88
means how can this help or improve things.
89
Renaissance means new interest or activity in something.
90
If something is out of favour,
91
it has become less popular or appealing.
92
And the adjective real-time means information is presented as it is happening.
93
Once again, our six minutes are up.

Por que praticar a fala com este vídeo?

Praticar a fala com o vídeo "Can AI solve crime?" (Pode a IA resolver crimes?) oferece a você uma oportunidade valiosa de se envolver em um contexto real e atual. O tema sobre como a inteligência artificial (IA) pode auxiliar na resolução de crimes é intrigante e relevant, proporcionando um cenário rico para o aprendizado. Além disso, a forma como os entrevistados falam sobre suas experiências e opiniões permite que você perceba mais sobre a estrutura da conversação em inglês.

Ao utilizar o método shadowspeak, você pode melhorar sua fluência, entonação e ritmo. Este método envolve repetir imediatamente o que você ouve, imitando o falante, o que ajuda a melhorar a pronúncia em inglês e a absorver novas expressões. Portanto, ao aprender inglês com YouTube, este vídeo não apenas ensina vocabulário, mas também como expressar ideias complexas de maneira clara e eficaz.

Gramática & Expressões em Contexto

No vídeo, várias estruturas importantes aparecem, que podem ser úteis para sua prática. Aqui estão algumas:

  • “Do you think…” - Uma forma comum de questionar a opinião de alguém, facilitando diálogos informais.
  • “I’m looking at…” - Usada para indicar interesse ou foco em um tópico específico, comum em conversas profissionais.
  • “Can AI help…?” - Estrutura que permite debater a capacidade de algo ou alguém de auxiliar, útil para debates e discussões.
  • “What can it do for me?” - Uma ótima expressão para personalizar discussões, mostrando que você busca relevância pessoal nas informações.

Incorporar essas estruturas na sua prática de shadow speech pode enriquecer seu vocabulário e melhorar sua capacidade de se expressar em inglês.

Armadilhas Comuns de Pronúncia

Mesmo com o conteúdo rico do vídeo, alguns desafios de pronúncia podem surgir. Aqui estão algumas armadilhas comuns:

  • “Intelligence” - A pronúncia desta palavra pode causar confusão devido à sua silabação; é importante praticá-la várias vezes.
  • “Evidence” - Prestar atenção ao som da letra “v” e ao ritmo da palavra ajudará a evitar pronúncias incorretas.
  • “Detective” e “investigation” - Ambas as palavras têm sílabas tônicas que podem ser difíceis; praticar seu uso em frases pode facilitar a fluência.

Ao se concentrar nesses aspectos, você irá melhorar a pronúncia em inglês e sua habilidade de se comunicar efetivamente. Não hesite em repetir as partes desafiadoras do vídeo até atingir a pronúncia desejada!

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
