Not hard to find if 'Thaksin's clip' is real: Forensic Cop
THE NATION

BANGKOK: -- The sophisticated technology of today could quickly and easily determine if the two men in an audio clip conspiring to bring former PM Thaksin Shinawatra back to Thailand were actually Thaksin and Deputy Defence Minister Yuthasak Sasiprapha.

"If a clip is fake, you can see that the graph will rise and fall," Pol Lt Colonel Watcharat Chalermsuksan, a director at the Central Institute of Forensic Science (CIFS), said yesterday.

Software like "Audacity" offered an easy and straightforward technique to dissect audio material by showing a sound graph, he said.

Besides the voices, listening to background noise can be a giveaway. Fake clips do not have the same background noise, he said.

"It is also easier to determine whether a clip is doctored if we have the original," he said.

The clip that has gone viral has become another hot potato for the government.

While many believe it is genuine, Pheu Thai MPs claim it was made to sabotage the Yingluck government.

Audio frequency analysers have been widely used by various industries for some time, while the government can turn to the National Police's Scientific Crime Detection Institute and the Justice Ministry's CIFS for forensic investigation.

However, it is harder to detect a voice modified to sound like a specific person.

The National Electronics and Computer Technology Centre is developing a program to check voice authenticity that is 100 per cent correct.

The centre's equipment is 80 per cent accurate in terms of voice manipulation analysis.

Assoc Prof Sathon Vijarnwannaluk from Chulalongkorn University said it was more |difficult to determine if a voice is genuine or edited than to check if an audio clip is doctored.

"It may be easier to detect a manipulated voice in a spoken word but it is harder to detect it in a sentence,'' he said.

Examples of people whose voices have been imitated are popular Buddhist monk Phayom Kanlayano and even Thaksin, he said.

I don't think PT want to hear any sentence with the words rise and fall in them.

Besides this whole issue has never been about the truth, it's about preventing the truth coming out and damage limitation.

[NongKhaiKid]

Like everything else here the truth is easy to find if it's decided before hand.

Look how quickly Chalerm " solved " the motive in recent murder.

[Issangeorge]

Why hasn't a major newspaper sent a copy of the clip to a company in the States States that analyses these things?

Sent from my i-mobile IQ 6 using Thaivisa Connect Thailand mobileal app

[chainarong]

You don't need a forensic cop to sort this out, the two gentlemen concerned only have to tell the truth , now the forensic cop has he's work cut out.

[steffi]

Where is the clip I reckon I can tell Thaksin's voice from another. Has the clip been made publically available?

[Thaddeus]

Well there you go, if you want to learn how to produce fake evidence, ask a policeman.

nah they just rip and modify an existing program

way cheaper

would love to have a go at it also

i even have some hightech as headphones and way better programs than audacity

If the forensic police verify the tape, will they first ask, what answer does the government want?

No kidding ?

The article mentions a programme called audacity well this so called program is very low end almost amateur likeused by at home studio musicians .There are many programs that voice analysts use this is not one of them,

Agreed. That is a freeware program, and I do not think it will do anywhere near the job. A simple search on Google for "voice matching software" gives you much better choices.

Don't worry, the HUB of voice recognition is hard at work and has a suitable program in a few days

yes even specialists from abroad have difficulties testifying in court if a certain voice belongs to a certain person - see the ongoing Trevon Martin case in the US where not one single forensic expert could tell which one is shouting for help the suspect or the victim!

But it is easy for the Thai police to find out who the voices on this tape belong to with software you can buy in any computer shop!! hahahaha.....hahahahaha

[pedro01]

I think the cop is referring to the effects of splicing clips together in an audio file. That sort of thing would be easy to spot in audacity.

[belg]

i guess someone will be asking 200 million baht soon for some software ?

[ballpoint]

The very fact that there is even a grain of suspicion that an audio clip, which purports to reveal a deputy defence minister discussing the affairs of a nation, and its military leadership, with a convicted fugitive from justice, may be real, speaks far more about the problems facing this nation than the actual contents of the clip itself.

While many believe it is genuine, Pheu Thai MPs claim it was made to sabotage the Yingluck government.

No need to sabotage this government...they're doing a fine job on their own

[Katipo]

"While many believe it is genuine, Pheu Thai MPs claim it was made to sabotage the Yingluck government."

This is all you need to keep the PTP believes happy. Anyone who says anything different, is just trying to discredit the government.

[ezzra]

I'll lay bets that the tape will found to be by the "experts" as fake, or at best, "inconclusive"

my question is, who taped the conversation ? for what purpose or agenda?

[klauskunkel]

If the forensic police verify the tape, will they first ask, what answer does the government want?

...and second, how much you pay for the right results?

[khunken]

What I don't understand is why Chalerm hasn't pronounced the result.

The man in Dubai bought that company already and stopped distribution of all software, I wonder why?

The original recording is in digital form on someone's phone. Since it is in digital form, all copies are identical to the original with no degradation of quality. The youtube version would suffice for forensic testing. There is no desire, either by the police or the press, to prove this recording is genuine; especially when everyone 'knows' it is. Krieng Jai - the desire not to cause someone embarrassment or discomfort - is still a strong factor in Thai culture. This is why there is little investigative/expose' type reporting in Thailand; it is mostly quoting government sources or antigovernment sources. Reporters are afraid of lawsuits for libel if they cannot expose their methods or sources.
