Rhinoflowmeter is an effective tool for collecting and analyzing articulatory aerodynamic data，It is also a universal tool for clinical diagnosis and evaluation of patients with velopharyngeal closure problems。The rhinoflow Bet365 gamesmeter of Shandong University Speech Laboratory is produced by Glottal，It is non-invasive、Easy operation and portability。

1. Hardware system

Adult Oronasal Mask、Children’s Oronasal Mask、Mask handle、Mouth and nose separation handle (including narrow、中、Removable dividers in three widths)、Microphone、USB cable

2. Instrument connection

Oronasal flow measurement: Install the oronasal mask on the mask handle，Connected to computer via USB cable。

Nasalization measurement: Connect the oronasal separation handle with microphone to the computer via USB cable。

bet365 online sports bettingNote: After the connection is completed，Need to set the computer’s sound recording to two-channel。

3. Signal collection

Oronasal flow signals are collected through the nasal flow system，Nasalization signal is collected through the nasalization system，Recording uses dual channels，The first channel is the nasal cavity signal，The second channel is oral signal。The signal needs to be calibrated by "zeroing" before recording，Use alcohol pads to clean and disinfect the mask after use。

(Insert Figure 3-1, Figure 3-2)

4. Data analysis

Extract and analyze aerodynamic bet365 live casino gamesparameters in real time through the rhinoflow meter’s built-in software，includes nasality、Port traffic、Nasal flow, etc.。

5. Application fields

Linguistic research: nasal flow and nasal pressure data can make up for the shortcomings of acoustic analysis，Important pronunciation facts showing some phonetic phenomena，such as voiceless nasals and nasalized vowels；

Speech Pathology Study: Clinical Assessment of Velopharyngeal Insufficiency、Correction and rehabilitation training；

Forensic Language Research: Individual differences bet365 online sports bettingin nasal parameters can be used to identify phonetic identity。
