Would a kenku be able to use this spell to approximate speaking?

 But can you move it?

my dad made my character and i cept telling him "I DON'T WANT THIS" but he did not listen AT ALL

Could a character use this spell to modify an existing sound? I.e. to distort a voice?

Margarita_Sorennodel No. The reason Kenku can't speak normally isn't about physical inability to speak, it's about mental inability to say original thoughts. A Kenku can speak as long as it's something they've heard other people say. If someone spoke the entirety of War and Peace aloud and the kenku somehow memorized it, they could recite that perfectly, but even minor illusion would not allow them to articulate original thoughts. 

Well, my player's going to be very disappointed to hear that. :)

I dont think you understood what I said, you can definitely make sonic sounds that can be perceived as real. But it will not confuse a bat because a bats echolocation will not be disrupted regardless of however many other sounds are being made around it, because its echolocation is not the same as the bats echolocation next to it. So if you made a sonic illusion without extensive study on how to make a sound that effects multiple bats in the region, you will be extremely lucky to make a "sonic" rock look real to a single bats echolocation. 

 i would hate to have you as a DM.

 Both bats have the same organs for sensing sound & interpreting that data as a physical shape.

If the sonic illusion can't fool 2 different bats' echolocation, why does a visual illusion fool 2 different humans' eyesight?

 Ooh, this one I know :)

Echolocation in bats is not just 'seeing with sound' as we might say as a shorthand explanation. Bats can't build a mental picture of all sounds they hear because otherwise something silent would be invisible to them. Instead, the sounds they use to build a mental picture are clicks that they make themselves. The time lag between the production of the click and hearing it's echo tells the bat how far away an object is. 

Compare that to how we see - light from a source reflects off an object and enters our eye. We don't produce the light ourselves.

Applying that to minor illusion, the idea of the spell is that it produces the appearance of an object or a sound. It is reasonable to imagine that this light would be interpreted by any eyeball as light reflecting off an object, however it is unreasonable to imagine that the spell fools an animal into believing it made a sound that it didn't.

Expanding this more widely to blindsight, in general creatures with blindsight could be thought to be immune to a visual minor illusion, but would still be aware of a sound that the spell made (assuming they had some sensitivity to sound, snakes for example have no ears but are aware of vibrations in the ground such as heavy footsteps).

Tldr: bats make the sounds they 'see' so echolocation and sight are fundamentally different.

 i mean how do we know how a dog or wolf sees or a giant insect? if the player wanted to try and mimic the sounds a bat makes with echolocation, obviously the bat would know that it didn't make that sound...but then we get into how do bats interpret other bats clicks....? maybe that's enough to confuse another creature with echolocation? 

The range of the sound is only within the 5ft cube, so unless a creature enters that 5ft cube they would not hear any sounds, blindsight, echolocation or otherwise.

 Your eyes aren't identical to the eyes of the person next to you, either. A bat echolocates very much like every other bat of its species (&, indeed, very much like every other bat), so why should an illusion that works on vision need to be attuned to a specific bat? I might believe a limit on a particular species of bat, but even that's a bit of a stretch, IMO.

In mad mage my illusion wizard used this to block a spell can’t remember which one

But the real question is can you use it to create musical accompaniment?

But there isn't a verbal component.

Concept: You know people are about to come over to eat or something, and you replace a few chairs with minor illusion versions. nobody realizes it until they try to sit down.

Arcane Trickster creates an illusion of cover like a bush or rock, hides, and then gets sneak attack with advantage.

No. Effects of the spell end when cast again.

Can the caster alter the image of the object to simulate movement? (e.g. an illusion flag that flaps in the wind)
Can the caster place the image over an existing object to hide it? (e.g. create an illusion chest over a book, book no longer visible because of the chest)
Can the caster make the image look like the background to simulate invisibility? (I think this one speaks for itself.)

If the previous two statements are answered yes, can you simulate "alter self" for one minute using this spell (although you can only change five feet of you if you're taller than that and must stand still)?
Can the caster create an image of a black box around an enemy's head, simulating blindness until the enemy steps out of the box?

Can the caster move the image around? (e.g. to move the black box with the enemy's head, sustaining blindness for a minute, or to allow movement while simulating alter self) 

Can the caster create sounds that cancel out other sounds, thereby muting sounds?

I think so. The spell creates a scratchy sound that, when overlayed with the voice, distorts it.

Or, the caster could just fabricate a new voice and cast that.

It's my understanding that you can't make images of creatures with this spell, that the intention is simple objects only.

Are there any feats or features that extend the range of Minor Illusion? It'd be useful to be able to cast it 60' away.

Nevermind. I just saw Metamagic Adept.
