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.
94

95
Goodbye for now.
96

Informazioni su Questa Lezione

In questa lezione, esploreremo l'utilizzo dell'intelligenza artificiale nella risoluzione dei crimini. Attraverso la discussione tra i presentatori, avrai l'opportunità di praticare la comprensione orale mentre apprendi come la tecnologia sta cambiando le tecniche investigative della polizia. Imparerai anche frasi e vocaboli chiave che possono aiutarti a esprimere opinioni e a discutere di temi legati alla criminalità e alla tecnologia, migliorando così la tua capacità di conversazione in inglese.

Vocabolario e Frasi Chiave

  • Investigare - to investigate
  • Prove - evidence
  • Intelligenza artificiale - artificial intelligence
  • Alias - to represent a specific perspective
  • Risoluzione di crimini - crime-solving
  • Fondamenta - background (in un contesto di esperienza)
  • Motivi - patterns

Consigli per la Pratica

Per migliorare la tua pronuncia inglese e il tuo ascolto, ti consiglio di fare shadow speak con il video. Poiché il ritmo di conversazione in questo episodio è moderato, hai buone possibilità di seguire i presentatori. Ecco alcuni suggerimenti specifici:

  • Ascolta attentamente il dialogo almeno una volta senza interrompere. Cerca di afferrare il contesto e le emozioni espresse.
  • Rivedi il video, questa volta fermandoti dopo ogni frase per ripetere ciò che hai sentito. Questo ti aiuterà a migliorare la pronuncia e l'intonazione.
  • Utilizza la funzione di riproduzione lenta di YouTube se necessario. Questo ti permette di valutare meglio i suoni e le parole.
  • Annota espressioni e vocaboli che trovi difficili e ripetili regolarmente. Creare delle frasi con questi termini ti aiuterà a coglierne il significato e l’uso nel contesto.
  • Infine, considera di fare delle sessioni di shadowspeaks in cui parli con amici o tutor sull'argomento trattato nel video, praticando così sia il vocabolario che le strutture della lingua.

Seguendo questi passaggi, non solo migliorerai le tue capacità linguistiche, ma acquisirai anche una comprensione più profonda del linguaggio utilizzato nel contesto delle forze dell'ordine e della tecnologia.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
