Armenia is holding a parliamentary election seen as a test of the country's commitment to democracy.
The governing Republican Party led by Prime Minister Serzh Sarksyan is expected to defeat the opposition.
This is Armenia's fourth election since it gained independence in 1991. Foreign monitors said the last poll, in 2003, did not meet democratic standards.
Ahead of the vote Western countries have warned of serious consequences if Armenia does not improve this record.
"The real test is on election day and during counting," a spokesman for the Organisation for Security and Co-operation of Europe (OSCE) monitors told Reuters news agency.
"That is a corner stone," he added.
If there is evidence of fraud, Armenia could lose more than $200m (£101m) of American development aid and the possibility of closer links with the European Union, the BBC's Matthew Collin in Yerevan says.
These are vital for the future of this small, impoverished and isolated country, our correspondent says.
'Buying support'
Polling stations across Armenia opened at 0800 local time (0300 GMT).
About 2.3m voters are registered to elect 131 members of the country's National Assembly.
The start of the campaign was marred by a series of violent attacks.
Questions were also raised about the conduct of some politicians who had been offering gifts to potential voters.
Our correspondent says some opposition parties believe the vote will be rigged so Armenia's elite can retain its wealth and power.
Critics have accused the authorities of trying to silence dissent and have vowed to launch protests after the elections.
Officials say that changes in the country's electoral law will make these polls more democratic.
Armenia fought an unresolved war with neighbouring Azerbaijan over the Nagorno-Karabakh region after the break-up of the Soviet Union in the early 1990s.
Yerevan also has fraught relations with Turkey.
Earlier this week, Armenia angered OSCE by refusing to grant visas to eight Turkish members of its 400-strong group of foreign observers.
