The voice recording of Nora Quoirin's mum will be played over loudspeakers in a bid to find the missing British teenager.
The 15-year-old disappeared from a resort in Malaysia on Sunday and more than 200 people have been involved in the the rescue operation, working on shifts through the night as well as a helicopter search.
But police have been baffled by a lack of evidence and information in the case.
District police chief Nor Marzukee Besar believes Nora is "still within our search vicinity".
He told reporters: "We would like to use voice recordings of her mother and use loudspeakers to call her out, whether it's Anne or Nora or whichever name the missing person is familiar with, or even use her siblings' voices."
Nora arrived with her family, including her two siblings, at the Dusan forest eco-resort, located about 39 miles south of the capital Kuala Lumpur, on Saturday.
The teenager's family, from London, believe she was abducted on Sunday, but police are treating her as a missing person, although they have refused to rule out a "criminal element" in her disappearance.
Police have analysed fingerprints found in the resort cottage from which Nora was reported missing.
The prints were at an open window in a downstairs hall, not in the bedroom upstairs where Nora was sleeping with her siblings, deputy police chief Che Zakaria Othman said.
Investigations are still ongoing to identify who the fingerprints belong to.
Nora's family released a statement expressing its “deepest gratitude” to the Royal Malaysia Police and others helping the search.
The family’s statement said: “We would like to thank our embassies, the local community, and the staff here at the hotel and anyone else who has offered help to find Nora.
“We also welcome the assistance of the French, British and Irish police.
“We are completely overwhelmed by the support we have received from all over the world.”
The teenager's parents, Meabh and Sebastien, an Irish-French couple, were “too upset to speak themselves at this time”, said the statement released on their behalf by the Lucie Blackman Trust, which helps crisis-struck British nationals overseas.
“This is extremely traumatic for the whole family,” it said.
The statement added: “We must remain hopeful.
“And we ask everyone to keep Nora in their thoughts, and to continue to support the ongoing search for her.
“Nora is still missing, and she is very vulnerable, and we need to do everything we can to bring her home.”
