Objective.　Slantwise-placed　electroglottography　(EGG)　was　proposed　for　synchronous　use　with　an　ultrasound　machine　in　a　previous　work.　The　objective　was　to　confirm　the　feasibility　of　this　slant　EGG,　differentiate　it　from　conventional　EGG,　and　give　suggestions　for　its　applications.　Study　Design　and　Methods.　A　synchronized　system　composed　of　an　EGG　device,　a　high-speed　video,　a　sound　level　meter,　and　a　headset　was　established.　The　same　phonation　conditions　were　acquired　by　training　subjects　to　reach　the　target　phonation　frequency　and　intensity.　Electrode　position　was　designed,　and　vocal　fold　vibration　parameters　were　measured　from　EGG　waveforms　recorded　in　each　electrode　position.　Results.　Comparison　showed　that　the　characteristic　points　identified　in　slant　EGG　waveforms　were　consistent　with　the　vibration　phase　shown　by　high-speed　video　images.　Phonation　frequency　measured　from　slant　EGG　was　highly　accurate.　EGG　amplitude　nonlinearly　decreased　with　the　increase　of　electrode　distance.　Compared　with　conventional　EGG　parameters,　velocity　ratio　and　glottal　closed　quotient　measured　from　slant　EGG　were　accurate　when　electrodes　were　placed　symmetrically　and　the　electrode　distance　was　within　a　proper　length.　Conclusions.　Slant　EGG　was　proved　feasible　and　can　be　considered　as　a　useful　tool　to　obtain　comprehensive　information　in　investigating　the　in　vivo　vocal　fold　dynamics　when　synchronized　with　other　detecting　equipment.
